Vapour pressure of dilute solution of gl...

Vapour pressure of dilute solution of glucose is 750m of mercury at 373K. The mole fraction of solute is

A

`1//76`

B

`1//7.6`

C

`1//38`

D

`1//10`

Text Solution

Verified by Experts

The correct Answer is:
A
At `373 K (100^(@)C)` V.P. of water, `P^(@)=760 mmHg, P_(s) = 750 mmHg`
`(P^(@)-P_(s))/(P^(@))=x_(B)`
`(760-750)/(760)=x_(B)`
`x_(B)=(1)/(76)`
