How do you calculate the molar mass

WebThe mass. of a substance in grams can be calculated from its amount in moles and its molar mass: mass (g) = molar mass (g/mol) × amount (mol) Example. Calculate the mass … WebThe former has a molar mass of 12 g/mol, and the latter a molar mass of 16 g/mol. Since there are 2 moles of oxygen atoms in every mol of carbon dioxide, the total molar mass due to oxygen is 2 x 16 g/mol = 32 g/mol. The resulting molar mass of carbon dioxide is therefore 12 g/mol + 32 g/mol = 44 g/mol.
