The molal depression constant of water is …………….while that of benzene is ……………… .

Explanation

To answer the question regarding the molal depression constant of water and benzene, we will follow these steps:

### Step 1: Understand the Concept of Molal Depression Constant
The molal depression constant (Kf) is a property of a solvent that indicates how much the freezing point of the solvent decreases when a solute is dissolved in it. The formula for calculating the depression in freezing point (ΔTf) is given by:
\[ \Delta T_f = K_f \times m \]
where:
- ΔTf is the depression in freezing point,
- Kf is the molal depression constant of the solvent,
