A sophister student in the Cocker Lab measures a vapour pressure
of 50 torr for a solution containing 250 g of an unknown
substance in 75 ml of benzene at 25 ºC. What is the molecular
weight (in g/mol) of the unknown substance?
Data: The vapour pressure of pure benzene
at 25 ºC is 192 torr. The density of benzene at 25 ºC is 876.6
kg/m3.
