WebJun 28, 2015 · Osmolality of a solution is the number of osmoles of solute per kilogram of solvent. The main difference between this and the definition of osmolarity is that the definition uses the mass, rather than the volume, of the solvent. There are several reasons for this, of which the main is the dependence of solvent volume on things like temperature.
