The iron content of iron ore can be determined by titration with a standard KMnO4 solution. The iron ore is dissolved in HC1, and all the iron is reduced to Fe²+ ions. This solution is then titrated with KMnO4 solution, producing Fe³+ and Mn²+ ions in acidic solution. If it required 34.08 mL of 0.0510 M KMnO4 to titrate a solution made from 1.957 g of iron ore, what is the mass percent of iron in the iron ore? Mass percent = %
