What is the mass in grams of 100 atoms of carbon -12 isotope?

Answers

Answer 1
100 atoms is the same as how many moles?

  nº atoms /avogadre number= nº of moles

  100/6,022x10^23=  1,66x10^-22 moles
 
the molar mass is: mass/moles

we know that the molar mass of carbon 12 it's the same as his atomic number, which is 12.

So, using the previous formula:   
 
12= mass/ 1,66x10^-22
mass= 1,992x10-21 grams of carbon 12


Answer 2

Answer:

The mass of 100 atoms of carbon-12 isotope is [tex]1.67377 \times 10^{-22} \texttt { g}[/tex].

Explanation:

Given carbon is carbon- 12 isotope. The number of atoms of carbon is 100.

Now, the mass of 1 carbon -12 atom is,

[tex]m=12\texttt { u}\\m=1.67377 \times 10 -24 \texttt{ g}[/tex]

So, the mass of 100 carbon-12 atoms will be,

[tex]M=100\times m\\M=100\times 1.67377 \times 10^ {-24} \texttt{ g}\\M=1.67377 \times 10^{-22} \texttt { g}[/tex]

Therefore, the mass of 100 atoms of carbon-12 isotope is [tex]1.67377 \times 10^{-22} \texttt { g}[/tex].

Answers

Historians have argued that the settlement of the English colonies was undertaken in a haphazard manner, with little regard to the geography, climate, peoples, or practical demands of the New World. this is true, the basis for the setelers coming to America was haphazard. They came to America to seek refuge from the Huge restrictions of the British monarchy. When they got here they did nothing but Industrialize start wars and kill Indians. When they first came they brought with them deadly (to the Indians) diseases, and also contracted deadly diseases. That happened for a good decade. After that they continued to go about steeling the land form the Indians and turning it into their land. The made countless treaties and broke almost all of them. Then they fought for independence and won leaving everything in shambles. After that came the great industrialization which drained energy and lively hood out of the geography. Every thing down to the very reason they came was done in a very haphazard way.

Historians have argued that the settlement of the English colonies was undertaken in a haphazard manner, with little regard to the geography, climate, peoples, or practical demands of the New World. I believe that this statement would be correct because the English came here in search for religious freedom from the laws of England and they made their way into America. From that moment on, they had made the best of the land that they were provided with, they had fights with the Indians that lived on the land, they had searched for treasure, they had gone through tormenting sicknesses and harsh winters, and in all of that craziness, they destroyed their land. The pilgrims had killed multiple Indians, made treaties with the Indians and then broke them, and they had also gone into war with Britain two times. This was a very haphazard way of living and their lives were very disorganized but even though it was very hard, they still persevered.

What are the basic tenets of Confucian thought?

Answers

Final answer:

Confucian thought emphasizes the importance of virtuous leadership, observing rituals, and fulfilling duties to the leader's subjects. Family relationships and the concept of ren are also central to Confucianism, promoting obedience, honor, and an attitude of generosity and empathy.

Explanation:

A central tenet of Confucianism is the importance of exemplifying virtuous leadership by living a moral life, studiously observing rituals, and being tirelessly devoted to the duties owed to the leader's subjects. Confucian texts such as the Book of Documents promoted habits like literacy, critical thinking, the search for universal truth, humility, respect for ancestors and elders, and the valuing of merit over aristocratic privilege.

Confucius also considered family relationships to be central to an orderly society. Specifically, he delineated five cordial relationships between king and subjects, father and son, husband and wife, elder brother and younger siblings, and friends. Each relationship consisted of an authority figure who required obedience and honor from the other person or persons, except for friends who were to honor one another. In return, the person in authority was supposed to embody ren, an attitude of generosity and empathy for those beneath him. So long as everyone behaved as they should, good order would flourish.

Which two colonies did not declare their independence during the 1800s?

Answers

the US and the Spanish

Final answer:

The question seems to be based on a misunderstanding since all territories that were colonies in the 1800s eventually declared independence, albeit at various times.

Explanation:

The colonies that did not declare their independence during the 1800s were not the original thirteen colonies that declared independence from Great Britain in 1776, as these had already done so. The question might be referring to colonies that did not become independent during the wave of decolonization in the 19th century. However, based on historical records, every territory that was a colony in the 1800s eventually moved towards independence, although at different times. The question might be based on a misunderstanding or might require clarification regarding specific regions, as the territories under colonial rule in the 1800s were numerous and varied across different parts of the world.

How did installment plans affect the american economy in the 1920's?

Answers

Installment plans helped the American economy to grow during the 1920’s. As more modern appliances were being produced, installment plans helped people who were not rich to be able to purchase these items. Because the middle class was able to purchase these items, demand was high which created more jobs for people in factories and more opportunities for companies to grow.
Final answer:

Installment plans of the 1920s boosted the American economy by stimulating consumer spending and increasing production and employment in the manufacturing sector. However, they also created a cycle of debt that was exacerbated by the Great Depression.

Explanation:

The installment plans of the 1920s had a significant influence on the American economy. These plans allowed consumers to buy goods over an extended period of time without having to pay the full price upfront. The result was a surge in consumer spending which greatly stimulated the economy.

Companies and businesses benefited from increased sales. As the demand for products, like cars and household appliances, grew so did the production. This led to more job opportunities and a boom in the manufacturing sector.

However, these installment plans also ignited a cycle of debt. Many people were buying goods beyond their means leading to large amounts of personal debt. When the Great Depression hit in the late 1920s, many individuals defaulted on their installment plans amplifying the economic crisis.

What were the dates of the 4 crusades

Answers

The dates of the 4 crusades is 1231 to 1234 hope this helped

Final answer:

The First Crusade was from 1096 to 1099, the Second from 1147 to 1149, the Third from 1189 to 1191, and the Fourth from 1202 to 1204. They were significant both for their military objectives and their impact on cultural and economic exchanges between Europe and the Eastern Mediterranean.

Explanation:

The historical events known as the Crusades occurred over a two-century span. The First Crusade began in 1096 and continued until 1099. It notably ended with the capture of Jerusalem and the massacre of its Muslim and Jewish inhabitants. The Second Crusade occurred between 1147 and 1149, called in response to the fall of the County of Edessa, one of the Crusader states. The Third Crusade spanned from 1189 to 1191, primarily to recapture Jerusalem following its conquest by Muslim forces led by Saladin. The Fourth Crusade, which lasted from 1202 to 1204, diverted from its initial goal, ultimately resulting in the sack of the Christian city of Constantinople.

While these military campaigns sought to establish Christian dominions in mostly Muslim-controlled lands, they also facilitated economic and cultural exchange between Europe and the lands of the Eastern Mediterranean. This exchange included the introduction of new goods such as silk and sugar to Europe.

What did foreign observers note about russia in terms of its size and population density?

Answers

The observers said that Russia was really large with heavy population density.
The nation filled with many trade centers, docks, churches, schools,  manufacturing companies, tourist attractions, warehouses, academy, etc. As far as the observer's could see, Russia is one big impregnatable fortress for its potential invaders
Final answer:

Foreign observers often commented on Russia's vast size and sparse population distribution. These aspects presented considerable impediments to its industrialization and economic development, further manifesting in its military capability, especially when compared with other industrializing countries at that time.

Explanation:

Foreign observers often noted the immense size and sparse population distribution across Russia. These factors critically influenced the country's rate of industrialization, economic development, and military might. The size of Russia was indeed a challenge to industrialize as its vast expanse was difficult to traverse and the rich natural resources required for industrialization were scattered and far from city centers. Industrializing nations such as the United States, although large, were not as large as Russia, and resources were more easily accessible.

Another key difference spanned from the population density. Russia's population consisted mainly of serfs bound to the land, unlike in the U.K. or U.S where people could migrate to factories for employment. This, combined with a relative lack of artisans, significantly hampered industrialization efforts. Observers further noticed that even with a larger populace than its European counterparts, Russia had a weaker military power, attributed to its inadequate industrialization.

Overall, in comparison to other countries undergoing industrialization in the same period, Russia's vast physical size and unevenly distributed population proved to be significant obstacles to its developmental progress.
