A slag sample is known to contain all of its iron in the forms of FeO and Fe2O3. A sample of 1,000 g of the slag was dissolved in hydrochloric acid according to the usual method, then reduced with stannous chloride and finally titrated with a 0.02237 M solution of potassium permanganate, of which 28.59 mL were used. A second aliquot of the slag sample, weighing 1,500, was dissolved in a nitrogen atmosphere to further adjust the oxidation state of the iron, it was immediately titrated with the same potassium permanganate solution. If this second experiment required 15.60 mL of permanganate solution, calculate: a) The percentage of total iron in the slag. b) The percentages of the oxide FeO and Fe2O3
