How can you calculate the mass of the molecule in grams? Watch the video to learn how to calculate molar mass. Molar mass is a quantity that is very similar to molecular mass, molecular weight, formula mass, and formula weight. In order to calculate molar mass, we look at the formula to determine how many atoms of each type are in it, and then look at the periodic table to determine the atomic mass of each of the atoms. We will look at compounds containing polyatomic ions, and hydrate compounds.
