How to calculate the molar mass of a compound: •For elements, the molar mass is the same thing as the atomic mass. •For chemical compounds, it's the sum of the masses of all of the atoms in the molecule. •Example: CO 2 C: 12.01 grams x 1 atom = 12.01 grams O: 16.00 grams x 2 atom = 32.00 grams Total: 1mole of CO 2 = 44.01 grams
