WebInstead, since we know the molar mass of carbon dioxide, we can measure out a comparable mass. Carbon dioxide has a molar mass of 44.01 g/mol, so 7 moles of carbon dioxide corresponds to. 44.01 g/mol×7 = 308.07 grams. So if an experiment calls for 7 moles of carbon dioxide, we know that we need 308.07 grams of carbon dioxide.
