( A ) The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is $BaCl_2 > KCl > CH_3COOH > sucrose $
( B ) Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression
( C ) The osmotic pressure $(\pi)$ = MRT, where M is the molarity of the solution
( D ) Raoult's law states that the vapour pressure of a components over a solution is proportional to its mole fraction
