The freezing point depression constant ($K_f$) of benzene is $5.12\ K\,kg\,mol^{-1}$. 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):$\Delta T_f = K_f \cdot m = 5.12 \times 0.078$ $= 0.399$ K ≈ 0.40 K
