2 x (molar mass of O atoms) = 2 x (16.00 g/mol) = 32.00 g/mol. Molar mass for CO 2 molecules = 1 x (molar mass of C atoms) = 1 x (12.01 g/mol) = 12.01 g/mol + 2 x (molar mass of O atoms) = 2 x (16.00 g/mol) = 32.00 g/mol. 44.01 g/mol. Using Avogadro’s Number in Calculations. Now that we’ve seen Avogadro’s number, we can use this value to ... Moles and Molar Mass. The mole is the "counting unit" used by chemists to indicate the number of atoms, ions, molecules, or formula units present in a particular chemical 3. Add it all together and put units of grams/mole after the number. Example: Find the molar mass of sodium carbonate, Na2CO3.
