18g of glucose (C(6)H(12)O(6)) is added ...

`18g` of glucose `(C_(6)H_(12)O_(6))` is added to `178.2g` of water. The vapour pressure of water for this aqueous solution at `100^(@)C` is-

A

759.00 Torr

B

7.60 Torr

C

76.00 Torr

D

752.40 Torr

Text Solution

Verified by Experts

The correct Answer is:
D
`X_("solute")=(P^@-P)/(P^@)`
`(18/180)/(18/180+(178.2)/18)=(760-P)/(760)`
`:. P = 752.40` torr
