Directions: Solve the problem with a complete step-by-step solution. A 0.8040-g sample of iron ore is dissolved in acid. The iron is then reduced to Fe21 and titrated with 47.22 mL of 0.02242 M KMnO4 solution. Calculate the results of this analysis in terms of (a) % Fe (55.847 g/mol) and (b) % Fe3O4 (231.54 g/mol).
