In the following reaction, 48.26g of sodium permanganate, NaMnO4, is reacted with 59.50g of sodium sulfite. Assuming an excess of water, which reactant is the limiting reagent and how many grams of the excess reactant is left at the end of the reaction? 2NaMnO4 + 3Na2SO3 + H2O → 2MnO2 + 3Na2SO4 + 2NaOH
