The molarity of 900 gm of water is

WebApr 2, 2024 · Thus, the molarity of pure water is 55.56 moles per litre. So, option C is the correct one. Note: We have to change the unit of density of water from gm/ml to Kg/L to calculate the molarity of pure water. This is because the molarity is calculated per litre of the solution and we have to make sure that the units are the same. WebOct 2, 2024 · To convert grams to moles, the molar mass of the solute is needed, which can be found on certain periodic tables . Molar mass of K = 39.1 g Molar mass of Mn = 54.9 g Molar mass of O = 16.0 g Molar mass of KMnO 4 = 39.1 g + 54.9 g + (16.0 g x 4) Molar mass of KMnO 4 = 158.0 g Use this number to convert grams to moles.
