If an ideal solution is made by mixing 2 moles of benzene `(p^(@)=266mm)` and 3 moles of another liquid `(p^(@)=236 mm)`. The total vapour pressure of the solution at the same temperature would be

A

502 mm

B

248 mm

C

600 mm

D

250.6 mm

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(T)=P_("benzene")+P_("liquid")`
`=P_(b)^(@)x_(b)+P_(i)^(@)x_(i)`
`=((2)/(5)xx266)+((3)/(5)xx236)=248`
