Question : 89 of 90

Marks: +1, -0

Which of the following statement is false?

Two different solutions of sucrose of same molality prepared in different solvents will have the same depression in freezing point.
The osmotic pressure of a solution is given by the equation n = CRT (where C is the molarity of the solution).
Decreasing order of osmotic pressure for 0.01 M aqueous solution of barium chloride, potassium chloride, acetic acid and sucrose is BaCl2>KCl>CH3COOH > Sucrose
According to Raoult’s law, the vapour pressure exerted by a volatile component of solution is directly proportional to its mole fraction in the solution.
