what is the mass of aluminum
If we make the balanced equation between al giving al2o3, The number of aluminum atoms is two and the number of oxygen atoms is three. As we know the atomic masses of aluminum as 26.9815386 grams per mole and oxygen as 16.9994 grams per mole. Multiplying the number of atoms of each of these elements by its respective atomic weight and then adding them, the molecular weight of Al2O3 is 101.961276 grams per mole.
