Calculate the cryoscopic constant of a solvent if depression in freezing point of $0 \cdot 3$ m solution of nonelectrolyte is $0 \cdot 48$ K

Options:

Answer:

Solution:

The depression in freezing point is given by the formula:

$Δ T_{f} = i \times K_{f} \times m$

For a nonelectrolyte, the van't Hoff factor $i = 1$ .

Substituting the given values:

$0 \cdot 48 = 1 \times K_{f} \times 0 \cdot 3$

$K_{f} = \frac{0 \cdot 48}{0 \cdot 3} = 1 \cdot 6 K kg mol^{- 1}$

Answer: $1 \cdot 6 K kg mol^{- 1}$
