The vapour pressure of water at20^@Cis 1...

The vapour pressure of water at`20^@C`is `17.5mmHg`.if `18g`of glucose `(C_(6)H_(12)O_(6)`is added to `178.2g` of water at`20^@C`, the vapour pressure of the resulting solution will be,

A

`17.675 mm Hg`

B

`15.750 mm Hg`

C

`16.500 mm Hg`

D

`17.325 mm Hg`

Text Solution

Verified by Experts

The correct Answer is:
D
`P_(A) = P_(A)^(@) x_(A) = 17.5 xx (178.2//18)/(9.9 +0.1) = 17.325 mm Hg`.
