iron content of iron ore can be determined by titration with KMnO₄ according to the equation 8H⁺(aq) + MnO₄⁻(aq) + 5Fe²⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(l) A sample of iron ore with a mass of 1.535 g was dissolved with HCl and then treated with a reducing agent to convert any Fe³⁺ in the ore to Fe²⁺. Titration with 0.0455 M KMnO₄ solution required 59.15 mL of the solution 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 ore

Question
The iron content of iron ore can be determined by titration with KMnO₄ according to the equation
8H⁺(aq) + MnO₄⁻(aq) + 5Fe²⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(l)
A sample of iron ore with a mass of 1.535 g was dissolved with HCl and then treated with a reducing agent to convert any Fe³⁺ in the ore to Fe²⁺. Titration with 0.0455 M KMnO₄ solution required 59.15 mL of the solution 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 ore
