The vapour pressure of water at 20^(@)C ...

The vapour pressure of water at `20^(@)C` is 17.5 mm Hg. If 18 g of glucose `(C_(6)H_(12)O_(6))` is added to 178.2 g 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`.
