Which one of the following statements is false?

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

The osmotic pressure $\left(\mathrm{\pi }\right)$ of a solution containing a non volatile solute is given by the equation $\mathrm{\pi }=\mathrm{MRT}$  , where M is the molarity of the solution

Raoult’s law states that the vapor pressure of a component over a solution is proportional to its mole fraction in the solution

The correct order of osmotic pressure for 0.01M aqueous solution of each compound is ${\mathrm{BaCl}}_2>\mathrm{KCl}>{\mathrm{CH}}_3\mathrm{COOH}>$ sucrose
