I prefer to divide by multiplying by the inverse of the molar mass, "mol/g". however, the molar mass of sodium is 23g/mol. For the rest of the atoms on the periodic table, their molar mass tells you how many grams of each you need to have a mole of those atoms, or 6.02×1023 atoms of that element. Because 45.9 g is less than the molar mass of Zn, we expect the result to be less than 1 mole. It will calculate the total mass along with the elemental composition and mass of each element in the compound. What is the molar mass of C3 H8? Enter site. For example, if you want to find the molar mass of carbon, you would find the atomic mass of carbon on the periodic table, and this is equal to the molar mass in grams per mole.
