The benzene `(V.P. = 268 mm)` and ethylene chloride `(V.P. = 236 mm)` form ideal solution. The total pressure made by dissolving 2 moles of benzene and 3 moles of ethylene chloride will be

A

504 mm

B

248.8mm

C

255.2mm

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
`P_("Total") = (2)/(5) xx 268 +(3)/(5) xx 236`
`= 107.2 +141.6 = 248.8mm`
