Potassium permanganate, a strong oxidizing agent, is commonly used in titrations because of its significant purple hue in solution. An experiment was performed in which a sample of iron(II) chloride (FeCl2) was dissolved in water and titrated with potassium permanganate (KMnO4) according to the following balanced equation. KMnO4(aq) + 8 HCl(aq) + 5 FeCl2(aq) → MnCl2(aq) + 5 FeCl3(aq) + 4 H2O(l) + KCl(aq) If 27.12 mL of 0.1147 M KMnO4 was added to the solution to reach the end point, what mass of FeCl2 was in the sample?
