Distinguish between molarity and molality.

Text Solution

Verified by Experts

By definition, molarity (M) of a solution is the number of moles of the solute dissolved per litre of the solution and molality (m) is the number of moles of the solute dissolved per kilogram of the solvent. Therefore, in molarity, volume of the solution is considered while in molality, mass of the solvent is taken into consideration.
