Q. Which one of the following statements is false?

Raoult’s law states that the vapour pressure of a component over a binary solution of volatile liquids is directly proportional to its mole fraction

Two sucrose solutions of the same molality prepared in different solvents will have the same depression of freezing point

The correct order of osmotic pressures of $0.01 M$ solution of each compound is $B a C l_{2} > K Cl > C H_{3} COO H >$ Glucose

In the equation osmotic pressure $π = MRT, M$ is the molarity of the solution

The molecular weight of $N a Cl$ determined by colligative property measurement is less than its theoretical molecular weight

Correct answer is (b) Two sucrose solutions of the same molality prepared in different solvents will have the same depression of freezing point
