A `5.8%` solution of `NaCI` has vapour pressure closets to:

A

`5.8%` solution of urea

B

2m solution of glucose

C

1m solution of urea

D

`5.8%` solution of glucose

Text Solution

Verified by Experts

The correct Answer is:
B
`m = ((5.8)/(58.5))/(94.2) xx 1000 = 1.06`
So `2m` solution of glucose will have same vapour pressure of this `NaCI` solution.
