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

A

`0.02`

B

1

C

20

D

180

Text Solution

Verified by Experts

The correct Answer is:
A

Relative lowering `= ( W_(g))/(M_(g))=(M_(w))/(W_(w))=( 18)/(180)xx(18)/(90)`
`= ( 1)/(5) =0.02`
