oxides must be expressed in terms of the number of moles of oxygen atoms in that oxide per 100 grams of mineral. Step #2 - Multiply the “mole number” of each oxide by the number of oxygens in the oxide formula. The sum of all the resulting “oxygen numbers” (2.7705) is the number of moles of oxygen atoms per hectogram of mineral.
