WebJan 22, 2024 · Molarity – number of solute particles in a solution. The difference between osmolarity and molarity is explained by the van’t Hoff factor – the number of moles (not the mass or weight) of dissociated solute particles (ions) in a solute. For example, a 1 mol/L glucose solution does not dissociate; the van’t Hoff factor is, therefore, one. WebMolarity (M)=Moles of solute/Volume of Solution We know that volume increases on increasing temperature, and vice versa. Also, molarity is inversely proportional to volume.
