हिन्दीThe freezing point depression constant (\( K_f \)) of benzene is \( 5.12\text{ K kg mol}^{-1} \). The freezing point depression for the solution of molality \( 0.078\text{ m} \) containing a non-electrolyte solute in benzene is (rounded off upto two decimal places):
Correct answer · Option 2
\( 0.40\text{ K} \)
Explanation
\( \Delta T_f = K_f \times m = 5.12 \times 0.078 = 0.39936\text{ K} \approx 0.40\text{ K} \).
