A chemical engineer determines the mass percent of iron in an ore sample by converting the Fe to Fe2+ in acid and then titrating the Fe2+ with MnO4-. A 1.3271 g sample was dissolved in acid and then titrated with 47.02 mL of 0.03740 M KMnO4. The balanced equation is given below.8 H+(aq) + 5 Fe2+(aq) + MnO4-(aq) 5 Fe3+(aq) + Mn2+(aq) + 4 H2O(l)Calculate the mass percent of iron in the ore. ______________ %
