Web11 jul. 2024 · Question 11 Calculate the number of aluminium ions present in 0.051 g of aluminium oxide. (Hint: The mass of an ion is the same as that of an atom of the same element. Atomic mass of Al = 27 u) Class 9 ... 1 mole of Al2O3 = Formula mass of Al2O3 in grams = Mass of Al × 2 + Mass of O × 3 = 27 × 2 + 16 × 3 = 54 + 48 = 102 grams Web7 feb. 2024 · Explanation: We know that the charge on Aluminium ion is +3 (i.e. Al³⁺) while, the charge on Oxide ion is -2 (i.e. O²⁻). Therefore, the overall neutral Al₂O₃ compound has 2 Al³⁺ ions and 3 O²⁻ ions. Since, we can say that, 1 mole of Al₂O3 contains = 3 moles of O²⁻ ions So, 0.450 moles of Al₂O₃ will have = X g of O²⁻ Solving for X,
