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?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
