The molar mass is calculated by adding the atomic masses of two hydrogen atoms (2 x 1.008 g/mol) and one oxygen atom (1 x 15.999 g/mol).Compute Mass of Each Element. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in CaCO3*H2O: Molar Mass (g/mol) Ca (Calcium) 1 × 40.078 = 40.078. C (Carbon) 1 × 12.0107 = 12.0107. O (Oxygen) 4 × 15.9994 = 63.9976.As mentioned above, the molar mass is the mass of a substance in one mol of a substance. This means that you can always find how many grams there are in a mol of any substance by finding the molar mass. For example, the molar mass of water (H 2 O) is 18.02 grams per mol. This means there are 18.02 grams of water in one mol of water..
