B
Two sucrose solutions of the same molality prepared in different solvents will have the same depression of freezing point.
43%
C
The correct order of osmotic pressures of 0.01 M solution of each compound is $BaCl_2 > KCl > CH_3COOH >$ glucose.
29%
D
In the equation osmotic pressure $π = MRT,\, M$ is the molarity of the solution.
14%
Solution:
$ΔT_f = K_f × m$
$K_f$ is a characteristic of a particular solvent i.e., it will be different for different solvents.
