which is better for express concentration molarity or molality

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.But molality does not changes with temperature baecause the mass of the solvent does not change with change in temperature.

molality is best bcoz it doesnt change with temperature
