Luke WangOctober 27, 2009Mr. When we do that, we're going to get a redox reaction. How to calculate the mass of a particular isotopic composition. Answer Save. Potassium permanganate (KMnO 4), one typical strong oxidant, is used extensively in various applications.However, its impact on anaerobic fermentation of waste activated sludge is unknown. Potassium manganate is the inorganic compound with the formula K 2 MnO 4.This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. This paper therefore aims to investigate its effect on generation of short-chain fatty acids (SCFAs) and qualities of fermentation liquor and fermented solid sludge. It can be calculated by adding the relative atomic masses of its constituent atoms. Molar mass of KNO3 = 101.1032 g/mol Convert grams Potassium Nitrate to moles or moles Potassium Nitrate to grams.
