Is Al2O3 ionic or molecular?
Aluminium oxide (Al2O3) is not an ionic compound. It is a covalent compound.
How do I calculate molecular mass?
Multiply the atomic weight of each element with the number of atoms of that particular element. Similarly, do it for all the elements in the molecule or compound. Add up all the values obtained in the above step. Then add the unit as grams/mole you will get the molecular mass of the substance.
