1) If two liquids A (P°A = 100 torr) and B (P°B = 200 torr) which are completely immiscible
with each other (each one will behave independently of the other) are present in a closed vessel, the total vapour pressure
of the system will be,
a) less than 100 torr
b) greater than 200 torr
c) between 100 to 200 torr
d) 300 torr
2) when a liquid that is immiscible with water was steam distilled at 95.2°C at a total pressure of 748 torr,
the distillate contained 1.25 g of the liquid per gram of water.
The vapour pressure of water is 648 torr at 95.2°C; what is the molar mass of liquid?
1) 7.975 g/mol
b) 166 g/mol
c)145.8 g/mol
d) None if these
