One mole each of urea, glucose and sodium chloride were dissolved in one litre of water. Equal osmotic pressure will be produced by solutions of

A

glucose and sodium chloride

B

urea and glucose

C

sodium chloride and urea

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Solutions having same number of particles have same osmotic pressure.
`:.` Glucose and urea does not dissociate.
`:.` 1 more of glucose and urea will produce 1 particle.
`:.` Osmotic pressure of solutions of urea and glucose will be same.
