Which of the following statements is false?
(1) Two sugar solution of same molality prepared in different solvent will have the same freezing point depression
(2) Osmotic pressure \( (\pi) \) of a solution is given by \( \pi= \) MRT where M is molarity of the solution
(3) The correct order of osmotic pressure for \( 0.01 \mathrm{M} \) aqueous solution of each compound is \( \mathrm{BaCl}_{2}\mathrm{KCl} \) \( \mathrm{CH}_{3} \mathrm{COOH} \) Sucrose
(4) Raoults law states that the vapour pressure of a component over a solution is proportional to its mole fraction
