18 g glucose `(C_(6)H_(12)O_(6))` is added to 178.2 g water. The vapour pressure of water (in torr) for this aqueous solution is :

A

`7.60` Torr

B

`76.00` Torr

C

`752.40` Torr

D

`759.00` Torr

Text Solution

Verified by Experts

The correct Answer is:
C
`PA = P_(A)^(@) x_(A) = 760 xx (178.2//18)/((178.2)/(18)+(18)/(180))`
`= 760 xx (9.9)/(10) = 752.4` torr
