Calculate the vapour pressure of the sol...

Calculate the vapour pressure of the solution. The molefraction of the solute is 0.25. The vapour pressure of the pure solvent is 0.8atm.

Text Solution

Verified by Experts

`(p^(@)-p)/(p^(@))=x_(2)`
`(0.8-p)/(0.8)=0.25`
`p=0.6atm`
`"Vapour pressure of the solution = 0.6 atm"`
