WebMolar mass of KMnO4 = 39.1 g + 54.9 g + (16.0 g x 4) Molar mass of KMnO4 = 158.0 g. What other calculations you can do with the molarity calculator? mass of a compound of a solution calculation: Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol) volume of a solution calculation: Web1 mole = 6.02 x 1023 atoms (Avogadro’s number) When substances react, they do so in simple ratios of moles. However, balances give readings in grams. Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substance to another using moles, we must
