A 0.8040 g sample of an iron ore is dissolved in acid. The iron is then reduced to Fe2+ and titrated with 47.22 mL of 0.02242 M KMnO4 solution. Calculate the results of this analysis in terms of % Fe3O4 (231.54 g/mol). The reaction of the analyte with the reagent is described by the equation [4 Marks] 2 MnO4 + 10 Fe2+ + 16 H 2 Mn2+ + 10 Fe3+ + 8 HO
