Question

why does the molality of a solution remain unchanged with temperature​

Answer 1

Molality=no.of moles of solutes/mass of solvent in kg

As mass is independent of temperature, molality remains unchanged with temperature

Answer 2

ANSWER

We know that, molality= no. of moles of solute present in 1kg of solvent.

Here, we said about mass of solvent i.e. kg,

and we know that, mass can't be affected, therefore remain unchanged with change in temperature.

whereas in molality, Volume can be affected, therefore Changes with Change in temperature.
