If latent heat of fusion of ice is 80 cals per $g$ at $0^{o} C$ , calculate molal depression constant for water.

Options:

Answer:

Solution:

$K_{f} = \frac{R T_{f}^{2}}{1000 \times l_{V}}$ Here $R = 2 c a l s$ ,
$T_{f} = 0 + 273 = 273, l_{f} = 80 c a l s$
$K_{f} = \frac{2 \times 273 \times 273}{1000 \times 80} = 1.863$
