Differences between molar solution and molal solution:

Molar solution

1. The solution in which one mole solute remains in one litre solution is called molar solution.

2. Molarity changes with the change of volume of the solution.

3. Molarity changes with the change of temperature.

4. The unit of molar solution is mol/litre.

5. Molarity is less popular for measuring the concentration of the solution.

 

Molal solution

1. The solution in which one mole solute remains in 1000 gram solvent is called molal solution.

2. Molality changes with the change of mass of the solvent and independent of the volume of solution.

3. Molality does not change with  the change of temperature.

4. The unit of molal solution is mol/kg.

5. Molality is more popular for measuring the concentration of the solution.
