Question

Why molality is preffered over molarity ?

Answer 1

Answer:

Meaning: Molarity is number of moles per unit volume of the solution and molality is number of moles per unit mass of solvent. Volume is temperature dependent where as mass is constant at all temperatures.

Explanation:

So, molality remains constant but molarity changes with temperature. Hence , molality is preferred over molarity.

Answer 2

Answer:

Molality is the number of moles per unit volume of the solution and molarity is number of moles per mass of solvent...... So molality remains constant , but molarity changes with the temperature.............
