The iron content of iron ore can be determined by titration

The iron content of iron ore can be determined by titration with standard KMnO4 solution. The iron ore is dissolved in excess HCl and the iron reduced to Fe+2 ions. This solution is then titrated with KMnO4 solution, producing Fe+3 and Mn+2 in acidic solution. If it requires 41.95 mL of 0.0205 M KMnO4 to titrate a solution made with 0.6128 g of iron ore, what percentage of the ore was iron?
