WebAll you need to do is correctly enter your formula, choose whether you want a conversion from grams to moles or a conversion from moles to grams, and, in case of g to mol, enter the mass, or, in case of mol to g, enter the moles. Grams to moles example problem. Problem: Convert 25.0 grams of KMnO4 to moles. Solution: Web3 jan. 2024 · Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. photo of spine
