WebNow we need the molecular mass of the reactants and products: C a = 40 2 × O = 32 C a O = 56 3. We need to now calculate the moles of calcium used. We can use the mass provided and the molecular mass of calcium. The equation we are going to use is: moles (mol) = mass ( g) × Volume dm 3 We want moles so that means we need to rearrange the equation: WebCalculate the mass of aluminium that can be formed from 1020 g of aluminium oxide. 2A l 2 O 3 → 4A l + 3O 2 moles A l 2 O 3 = ࠵?࠵?࠵?࠵? ࠵?࠵?࠵? = 10.0 mol moles A l = 2 x 10.0 = 20.0 mol mass A l = 27 x 20.0 = 540 g REACTING MASS CALCULATIONS 1
