The vapour pressure of water at `20^(@)` is `17.5 mmHg`. 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 of Hg

B

15.750 mm of Hg

C

16.500 mm of Hg

D

17.325 mm of Hg

Text Solution

Verified by Experts

The correct Answer is:
D
`(P^(0)-P_(s))/(P^(0))underline~(n)/(N)implies(17.5-P_(s))/(17.5)=((18)/(180))/((178.2)/(18))impliesP_(S)=17.325mm`
