2. A 1.10 g sample of FeCl2 is dissolved in water and titrated with a KMnO4 solution. 35.30 mL of KMnO4 solution was needed to reach the end point. What is the molarity of KMnO4 solution? The Fe²+ ions in FeCl2 solution and the MnO4 ions in the KMnO4 solution react according to the molar ratio given by the following equation: 8 H+MnO4 + 5 Fe²+ Mn²+ +5 Fe³+ + 4 H₂O Show dimensional analysis steps. Report the molarity with appropriate number of significant digits. Hint: g of FeCl2 → moles of FeCl2 → moles of Fe²+ moles of MnO4 → moles of KMnO4 → Molarity of KMnO4

The iron content of iron ore can be determined by titration with a standard KMnO4 solution. The iron ore is dissolved in HCl, and all the iron is reduced to Fe²+ ions. This solution is then titrated with KMnO4 solution, producing Fe³+ and 3+ 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 = %
