The vapour pressure of pure liquid A at 310^@C is 0.158bar. The vapour pressure of this liquid in solution with liquid B is 0.095 bar. Calculate the mole fraction of A in the solution if the mixture obeys Raoult's law.
The vapour pressure of an aqueous solution of glucose is 750 mm of mercury at 100^@ C . Mole fraction of solute will be
100 g of liquid A (molar mass 140 g mol^(-1) was dissolved in 1000 g of liquid B (molar mass 180 g mol^(-1)) . The vapour pressure of pure liquid B was found to be 500 torr. Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.
Two liquids X and Y on mixing form an ideal solution. The vapour pressure of the solution containing 3 mol of X and 1 mole of Y is 550 mm of Hg. But when 4 mol of X and 1 mol of Y are mixed, the vapour pressure of the solution thus, formed is 560 mm of Hg. what will be the vapour pressure of the pure X and pure Y at this temperature?
The total vapour pressure of a 4 mole % solution of NH_(3) in water at 293 K is 50.0 torr. The vapour pressure of pure water is 17.0 torr at this temperature . Applying Henry's and Raoult's laws, calcilate the total vapour pressure for a 5 mole % solution:
Benzene and toluene form ideal solution over the entire range of composition. The vapour pressure of pure benzene and toluene at 300 K are 50.71 mm Hg and 32.06 mm Hg respectively. Calculate the mole fraction of benzene in vapour phase if 80 g of benzene is mixed with 100 g of toluene.
The lquid A and B from ideal solutions. At 300 K, the vapour pressure of solution containing 1 mole of A and 3 mole of B is 550 mm Hg. At the same tempreature, if one more mole of B is added to this solution, the vapour pressure of the solution increases by 10 mm Hg. determinethe vapour pressure of A and B in their pure states (in mm Hg):
