Determine the relative molecular weight of aluminum oxide. The following solution turns out.
M (Al2O3) = 27 * 2 + 16 * 3 = 54 + 48 = 102 g / mol.
Therefore, the relative molecular weight of the alumina is 102 g / mol.
Determine the relative molecular weight of magnesium hydroxide.
M (MgO) = 24 + 16 = 40 g / mol.
Therefore, the relative molecular weight of magnesium oxide is 40 g / mol.
