Given that `DeltaT_(f)` is the depression in freezing point of the solvent in a solution of a non-volatile solute of molarity `m`,the quantity `underset(m rarr0)(Lt) (DeltaT_(f)//m)` is equal to ……………. .

Explanation

To solve the problem, we need to analyze the relationship between the depression in freezing point (ΔTf), molarity (m), and the freezing point depression constant (Kf) for a non-volatile solute.

### Step-by-Step Solution:

1. **Understand the Formula for Depression in Freezing Point**:
The depression in freezing point (ΔTf) is given by the formula:
\[
\Delta T_f = K_f \cdot m \cdot i
