NEET 2020 Chemistry Colligative Properties MCQ Question
The freezing point depression constant (Kf) 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) :
0.40 K
0.60 K
0.20 K
0.80 K
Correct Answer
Detailed Explanation
The freezing point depression ΔTf = Kf × m = 5.12 × 0.078 = 0.40 K.
