Explanation:
The molar mass of a substance is the mass in grams of one mole of the substance.
When dealing with compounds the molar mass is the sum of the of its component atomic masses and expresses in grams per mole;
Given compounds;
Fe₂O₃ and Al₂O₃
Atomic mass;
Fe = 55.845g/mol
Al = 26.9185g/mol
O = 15.9994g/mol
Molar mass of Fe₂O₃ = 2(55.845) + 3 (15.9994) =
111.69 + 47.9982 = 159.7g/mol
Molar mass of Al₂O₃ = 2(26.9185) + 3(15.9994) = 53.837+47.9982
= 101.8g/mol
