The volume (in liters) and mass (in kg) of pure water are about the same (density is 1 kg/L). Molality is greater than molarity because the volume increases when the solute dissolves in water so now the volume of the solution is greater than the mass of the water.

0.1311 The percent by mass NaCl in the sample is % NaCl(by mass) = 0.3898 g NaCl 100. % = 43.9 % NaCl by mass. 0.8870 g sample. 132) The recommended procedure for preparing a very dilute solution is not to weigh out a very small mass or measure a very small volume of a stock solution. Instead, it is done by a series of dilutions.
