The inverted molar mass of aluminum oxide ([tex]\rm Al_2O_3[/tex]) is 0.00980 mole/gram.
Molar mass is the mass of one mole of a substance. It is expressed in units of grams per mole (g/mol).
To calculate the inverted molar mass of aluminum oxide as a conversion factor, you take the reciprocal of the molar mass.
= [tex]\rm \dfrac{1 \ mole\ \rm Al_2O_3}{102.\ g \rm \ Al_2O_3}[/tex]
= 0.00980 moles/g
Therefore, take the reciprocal of the molar mass to compute the inverted molar mass of aluminum oxide as a conversion factor. And 0.00980 mole/gram is the inverted molar mass of aluminum oxide.
