The molecular mass of `NaCI` as determined by osmotic pressure measurement is

A

`58.5`

B

less than `58.5`

C

more than `58.5`

D

unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B
`NaCI` undergoes dissociation in an aqueous solution. As such number of particles in solution increases, the magnitude of colligative property increases, molecular mass decreases.
