Question

With increase of temperature, which of these changes?

(1) Molality (2) Weight fraction of solute

(3) Molarity (4) Mole fraction​

Answer 1

$\large {Weight \: fraction \: of \: solute}$

Temperature will affect the volume of solution.

Hence, the expression for concentration that contain volume will change with temperature. Hence weight fraction of solute changes.

i.e. , Molarity gets effected with the change in temperature because the number of moles per unit volume changes by the change in temperature.

Answer 2

Temperature will affect the volume of solution.

Hence, the expression for concentration that contain volume will change with temperature. Hence weight fraction of solute changes.

i.e. , Molarity gets effected with the change in temperature because the number of moles per unit volume changes by the change in temperature.
