Distinguish between molarity and molality.

Text Solution

Verified by Experts

Molality it is defiend as the number of moles of solute dissolved in 1 kg of solvent it is independent of temperature.
Molarity it is defined as the number of moles of solute dissolved in 1L of solution depends upon temperature (because , volume of solution =temperature).
