The vapour presure of a dilute aqueous solution of glucose in `750` atom of fig `373 K` .The mole fraction of solute is

A

`(1)/(10)`

B

`(1)/(7.6)`

C

`(1)/(35)`

D

`(1)/(76)`

Text Solution

Verified by Experts

The correct Answer is:
d
`(P^(0) - P_(s))/(P^(0)) = (n)/(n + N)`
`(At 373 K V.P of H_(2)O = 760 min Hg)`
`(n)/(n +N) = (760 - 750)/(760) = (1)/(76)`
