Among the following mode of expression, the concentration of solution remains independent of temperature is

In molality method  the quantities of the solute and the solvent are expressed in weights, the molality does not change with the change in temperature.

$\therefore$  Molality is independent of temperature.

Molarity (M): The number of moles of a solute dissolved in one litre of the solution is known of the Molarity (M) of the solution.

$M=\frac{W}{GMW}\times \frac{1}{Vinlit}$     (or)

$M=\frac{W}{GMW}\times \frac{1000}{Vinml}$

Normality (N): The number of gram equivalents of the solute present in one litre of the solution is known as the Normality (N) of the solution

$Normality\left(N\right):\frac{W}{GEW}\times \frac{1}{Vinlit}$    (or)

$N=\frac{W}{GEW}\times \frac{1000}{Vinml}$

Formality: The number of gram formula units present in one litre of solution is called as formality.

Formality (F): $\frac{W}{GFW}\times \frac{1}{Vinlit}$    (or)

$=\frac{W}{GFW}\times \frac{1000}{Vinml}$

Molality, Normality and Formality.  These are dependent on temperature.
