Which from following statements is correct for aqueous solution of 6 g L ^ -1 urea and 17.12 g L ^ -1 of sucrose? [Molar mass of urea = 60 g mol^ -1 Molar mass of sucrose = 342 g mol^ -1 ]

MHT CET 2024 Chemistry question

Which from following statements is correct for aqueous solution of urea and of sucrose?

[Molar mass of urea = 60 g mol Molar mass of sucrose = 342 g mol]

(A)Osmotic pressure exhibited by urea solution is lower than that of sucrose solution
(B)Urea solution is hypertonic to sucrose solutionCorrect
(C)These solutions are isotonic
(D)On doubling the concentration of sucrose solution it becomes hypertonic to urea solution

Answer: (B)

Solution

Molarity of urea M. Molarity of sucrose M. Both are non-electrolytes, so osmotic pressure is proportional to molarity: . A solution with higher osmotic
