The iron content of a mineral deposit was determined by titration with KMNO4 to see if it had enough iron for processing. A sample of iron ore with a mass of 2.126 g was dissolved with HCl and then treated with a reducing agent to convert any Fe³+ in the ore to Fe²+. Titration with 0.0565 M KMNO4 solution according to the equation 8H*(aq) + MnO. (aq) + 5Fe²*(aq) → 5Fe*(aq) + Mn²*(aq) + 4H2O(I) required 23.25 mL of the titrant to reach the endpoint where the purple MnO4- ion was no longer being consumed. The molar mass of Fe is 55.85 g/mol. Determine the mass percent iron in the mineral deposit.
