The vapour pressure of pure liquids A and B are 450 mm Hg and 700 mm Hg, resprectively at 350 K. Find the composition of liquid and vapour if total vapour pressure is 600 mm. Hg.

What is vapour pressure of a liquid?

The vapour pressure of a liquid depends upon __________

At 300 K, two pure liquids A and B have vapour pressures 150 mm Hg and 100 mm Hg respectively. In an equimolar liquid mixture of A and B, the mole fraction of B in the vapour mixture at this temperature is:

The vapour pressure of a pure liquid A is 70 torr at 27^(@)C It forms and ideal solution with another liquid B. The mole fraction of B is 0.2 and the total vapour pressure of the solution is 84 torr at 27^@ C .the vapour pressure of pure liquid B at . the vapur pressure of pure liquid B at 27^(@)C is _____.

The vapour pressure of a dilute aqueous solution of glucose is 750 mm Hg at solution of glucose is 750 mm Hg at 373 K. The mole fraction of the solute is ______.

A mixture of benzene and toluene contains 30% by mass of toluene. At 30^@C , vapour pressure of pure toluene is 36.7mm Hg and that of pure benzene is 118.2 mm Hg. Assuming that the two liquids form ideal silutions, calculate that total pressure and partial pressur eof each constituent above the solution at 30^@C .
