Question

Identify the inappropriate statement.

• A. Osmotic pressure $(\pi )$ of a solution is given by the relation $\pi =MRT$ where M is the molarity of the solution.
• B. The correct order of osmotic pressure for 0.2M aqueous solutions of each solute is $CaC{l}_2>NaCl>C{H}_{3}COOH>$ glucose
• C. Two solutions of sucrose of same molality prepared in different solvents will have same elevation in boiling point
• D. Relative lowering in vapour pressure of a solution containing non-volatile solute is directly proportional to mole fraction of solute is Raoult's law

Answer 1

Answer: (C)

If there are different solvents, then the colligative properties changes. Since the elevation in boiling point is also a colligative property, it will not the same.
