In basic medium. Mno4- + 2H20 + 3e- –> MnO2 + 4OH- (n=3) Eq wt = 158.04/3 = 52.68g/Equivalent. In neutral The Mn in KMnO4 exists in +7 state. In Acidic medium, This Mn+7 goes to Mn+2 state and hence there is a net gain of 5 electrons. Now, equivalent weight = [molar mass] /[number of electrons gained or lost] so, eq wt = 158/5 = 31.6 g. Now, for alkaline medium, there are two possibilities 1) faintly alkaline/neutral: Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.
