The final mass of the oxide is 3.13 g. Determine the empirical formula of the oxide. Solution: 1) Determine mass: Cu ---> 2.50 g O ---> 3.13 g − 2.50 g = 0.63 g 2) Determine moles: Cu ---> 2.50 g / 63.546 g/mol = 0.03934 mol O ---> 0.63 g / 16.00 g/mol = 0.039375 mol This is a 1:1 molar ratio between Cu and O. 3) Write the empirical formula: CuO
Approx. 15⋅ g of metal. Explanation: Moles of iron oxide, F e2O3 = 21.6⋅ g 159.69 ⋅ g ⋅ mol = 0.135 ⋅ mol with respect to the oxide. But by the composition of the oxide, there are thus 2 × 0.135 ⋅ mol × 55.8 ⋅ g ⋅ mol−1 iron metal = ??g.
and, the atomic mass of Oxygen is 16 g/mol ∴ percent of iron in Fe2O3 = [(2*55.8) / ((3*16) + (2*55.8))] *100 = 69.92 % >>> (1) And if the mass of the iron is 58.7 g ∴ mass of Fe2O3 = 58.7 * 100 / 69.92 = 83.95 g >>>> (2) So, from (2), the mass of iron (III) oxide is 83.95 g and, from (1), the iron III oxide is 69.92 % iron by mass not 69.94%
