Review of Chemistry 11 - Mole Stuff . Part 1 - Changing Moles to Grams and Grams to Moles. The two conversion factors to remember are: Molar Mass(grams) & 1 mole. 1 mole MM grams. The Molar Mass is calculated by adding up atomic masses from underneath the symbol and the name on the periodic table. eg. The molar mass of Na2SO4 is calculated as follows: 2(23.0) + 32.1 + 4(16.0) = 142.1 grams ...
