To find the equivalent mass, divide that molar mass by the mols of electrons taken in its half reaction. That 2010-10-16 KMnO4 has a Molar mass of 158.04 g/mol Now, there are two possibillities: 1. KMnO4 as an oxidizer in acidic media: MnO4- + 8 H+ + 5e- --> Mn2+ + 4H2O (gained 5 electrons from reductant) and to find out the Eq.wt of any element we use the formula, or, 2.74 = weight in gram of KMnO4/158 or, weight in gram of KMnO4 = 2.74 × 158 g = 432.92 g hence, mass in gram of 2.74 mol of KMnO4 is 432.92g 1 moles KMnO4 to grams = 158.03395 grams. 2 moles KMnO4 to grams = 316.0679 grams.
