An aqueous solution of glucose was prepared by dissolving 18g of glucose in 90g of water. The relative lowering in vapour pressure is

A

6

B

0.2

C

5.1

D

0.02

Text Solution

Verified by Experts

The correct Answer is:
D
`(Deltap)/(p_(0))=x_(B)=(n_(B))/(n_(A)+n_(B))=((18)/(180))/((90)/(18)+(18)/(180))`
`=(0.1)/(5.1)=0.02`]
