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. WebJan 29, 2014 · Molecules with stronger intermolecular force have higher freezing points. > Let’s look at it from the point of view of a solid, where the particles are held in position by their intermolecular forces of attraction. If we raise the temperature enough to overcome these forces, the solid will melt. A solid with high intermolecular forces will require more … iowa paperboy disappearancesWebMolality is expressed in moles of solute per kilogram of solvent, while molarity is expressed as moles of solute per liter of solution.
