Why Molality has more benefits than Molarity ?

Description : Why Molality has more benefits than Molarity ?

Last Answer : The volume of solution changes with temperature change. So the unit malarity of the volume-based solution varies. But the mass of the object does not change with increasing temperature. Therefore, the ... But the malarity of the solution changes. So the benefits of malality are more than malarity.
