Density molality relation
WebJan 21, 2024 · This video explains how to calculate the concentration of the solution in forms such as Molarity, Molality, Volume Percent, Mass Percent, and Mole Fraction. It also explains how to calculate … WebThe density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore, the molar concentration of water is c (H 2 O) = 1000 g/L 18.02 g/mol ≈ 55.5 mol/L. Likewise, the concentration of solid hydrogen (molar mass = 2.02 g/mol) is c (H 2) = 88 g/L 2.02 g/mol = 43.7 mol/L.
