Total Vapour pressure of mixture of 1molA`(p_(A)^(0)=150 "torr")`and 2molB `(p_(B)^(0)=240 "torr")`is `200 "torr"`. In this case

Total Vapour pressure of mixture of 1mol A (p_(A)^(0)=150 "torr") and 2mol B (p_(B)^(0)=240 "torr") is 200 "torr" . In this case

Total vapour pressure of mixture of 1 mol X ( P_X^(@) = 150 torr) and 2 mol Y(P_Y^(@)) = 300 torr is 240torr. In this case :

Total vapour pressure of mixture of 1 mol X ( P_X^(@) = 150 torr) and 2 mol Y(P_Y^(@)) = 300 torr is 240torr. In this case :

Two liquids X and Y are perfectly immisoible. If X and Y have molecular masses in ratio 1:2 , the total vapour pressure of a mixture of X and Y prepared in weight ratio 2:3 should be (P_(X^(0))=400 torr, P_(Y^(0))=200 torr)

Two liquids X and Y are perfectly immisoible. If X and Y have molecular masses in ratio 1:2 , the total vapour pressure of a mixture of X and Y prepared in weight ratio 2:3 should be (P_(X^(0))=400 torr, P_(Y^(0))=200 torr)

Two moles of liquid A(P_(A)^(0)=100 torr) and 3 moles of liquid B(P_(B)^(0)=150 torr) from a solution having vapour pressure of 120 torr. Based upon this observation one can conclude:

The mole fraction of toluene in the vapour phase which is in equilibrium with a solution of benzene (P_(B)^(@)=120 "torr") and toluene (P_(T)^(@)=80 "torr") having 2.0 mol of each, is
