Solution:
If molality of the dilute solution is doubled, the value of molal depression constant $\left(\right.K_{f}\left.\right)$ remains unchanged. As molal depression constant $\left(\right.K_{f}\left.\right)$ is a characteristic property of the solvent. It has nothing to do with nature of solute or its concentration.
