The freezing point depression constant (KfK_f) of benzene is 5.12 K kg mol−1mol^{-1}. The freezing point depression for the solution of molality 0.078 m containing a non-electrolyte solute in benzene is (rounded off upto two decimal places) :

A

0.20 K

B

0.80 K

C

0.40 K

D

0.60 K

Step-by-Step Solution

Freezing point depression ΔTf=Kf×m=5.12×0.078=0.39936≈0.40\Delta T_f = K_f \times m = 5.12 \times 0.078 = 0.39936 \approx 0.40 K.
