Molar mass has units of grams per mole (g/mol). It is calculated by measuring the molecular weight of the chemical compound, which tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. We can compute the molar mass for you.
