B. To standardize a potassium permanganate solution, a 0.250 g sample of FAS (iron (II) ammonium sulfate hexahydrate; molar mass: 342 g) is dissolved in 25.00 mL distilled water, then acidified with sulfuric acid. The
solution is then titrated with 35.00 mL potassium permanganate solution from a burette until a pale persistent
purple color is attained. Calculate the molarity of the potassium permanganate solution.
