JEE Main 2007
Question
A solution of a substance is isotonic with a solution of urea molar mass ) in the same solvent. If the densities of both the solutions are assumed to be equal to , molar mass of the substance will be
Choose an option
Show full solutionCorrect option: D
Correct answer
D
Step-by-step explanation
Solutions with the same osmotic pressure are isotonic
Let the molar mass of the substance be
So,
As density of the solutions are same
So
Hence (D) is correct
