Molar Mass: 158.0339 KMnO4 is a dark purple crystal at room temperature. It is soluble in water. Molar Mass: Molar mass is the number of grams of a substance that equals to one mole or 6.02 x 10 23 molecules, also known as Avogadro's number. The unit for molar mass is g/mol. You can use molar Equivalent weight can be calculated by using the formula. Equivalent weight = Molar mass/number of electrons lost or gained (n) The molecular mass of KMno4 = 158.04g. In acidic medium: MnO 4-+ 8H +5e – –> Mn 2 + 4H 2 O. Here n = 5.
