Concept introduction:
The concentrations of solutions are expressed in different ways, all of them involved in the quantity of solute and the quantity of solution or solvent. Among them, molality is most appropriate unit to express the concentration of solution.Molality: Molality is defined as the number of moles of solute per kilogram of solvent. Molality is denoted by ‘m’. The volume of a solution changes with temperature, this change in volume alters the molarity of the solution. Masses, however, do not change with temperature. Molality does not change with change of temperature.
