If benzene toluene and para-xylene are mixed in molar ratio 1 : 2: 3. Estimate the bubble point pressure (At the bubble point pressure all liquid exist. No trace of vapour in mixture) for the above mixture.

Answer»

600 torr
170 torr
`(500)/(3)` torr
160 torr

Solution :At the bubble point PRESSURE all liquid EXIST. No trace of VAPOUR in mixture
`P_("bubble") = [(1)/(6) xx 300 + (2)/(6) xx 180 + (3)/(6) xx 120] = 170` torr
