two objects of different masses are sitting on a different balance scales. object A has a greater mass than object B how will the weights of the objects compare to each other?
Explanation:
Since it is given that object A has greater mass this means that object A is heavier than object B.
Therefore, when both object A and object B is placed on a balance scale on either side then the balance scale will move downwards on the side where object of heavier mass is placed.
That is, balance scale will be in downward direction where object A is placed. Whereas balance scale will move upwards where object B is placed.
carbon dioxide is a gas with the relative formula mass of 44. calculate the mass of the 36 dm3 of the CO2 at room temperature? ?? ANYONE WHO GET CHHEMISTY HELP
Final answer:
The mass of 36 dm3 of CO2 at room temperature is 66.02 grams, calculated by first determining the number of moles and then multiplying by the molar mass of CO2.
Explanation:
To calculate the mass of 36 dm3 of CO2 at room temperature, we can use the molar volume of a gas at room temperature, which is approximately 24 dm3/mol. Given that the molar mass of CO2 is 44.01 g/mol, we can first find the number of moles of CO2 by dividing the volume by the molar volume.
Number of moles = Volume / Molar volume = 36 dm3 / 24 dm3/mol = 1.5 moles
Now, to find the mass, we multiply the number of moles by the molar mass of CO2.
Mass = Number of moles × Molar mass = 1.5 moles × 44.01 g/mol = 66.02 g CO2
