Atomic Mass Of Sodium - QnA
WebJan 3, 2024 · Let's assume that you have 5 g of HCl in a 1.2 liter solution. 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. WebThat means that one mole of zinc weighs 65.38 grams (65.38 g/mol).
