Molality is considered better for expressing the concentration as compared to molarity because the molarity changes with temperature because of expansion or contraction of the liquid with temperature.

One is the ratio of moles to volume of the solution and the other is the ratio of molesto the mass of the solution.</p><p></p><p>Molality is better than the molarity concentration in chemistry praCtical calculation because Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.❖❖❖$
