The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 10 23 atoms and a mass of 12 grams. In comparison, one mole of oxygen consists, by definition, of the same number of atoms as carbon-12, but it has a mass of 15.999 grams. Oxygen, therefore, has a greater mass than carbon.
