WebHe used 20 mL of 0.02 M KMnO₄ from the buret for the titration, so he wanted to calculate the number of moles (0.0004 mol). Then he knew that he had 5 × 0.0004 mol of Fe²⁺ in the original sample. But the original sample had a volume of only 10 mL, so he used 10 mL to calculate its molarity. ( 12 votes) Alex Andres 8 years ago WebThe molar mass of potassium permanganate is 158 g/mol. To find the equivalent mass, divide that molar mass by the mols of electrons taken in its half reaction. That would be …
