WebTo convert grams to moles, the molecular weight of the solute is needed. From the periodic table the molar masses of the compounds will be extracted. For KMnO4: Molar mass of K = 39.1 g Molar mass of Mn = 54.9 g Molar mass of O = 16.0 g Molar mass of KMnO4 = 39.1 g + 54.9 g + (16.0 g x 4) Molar mass of KMnO4 = 158.0 g WebSo we're going to need 0.833 moles of molecular oxygen. And then I just multiply that times the molar mass of molecular oxygen. So, times 32.00 grams per mole of molecular oxygen. 0.833 times 32 is equal to that. If you go three significant figures, it's 26.7. 26.7 grams of oxygen, of molecular oxygen.
