A solution of 'A' and 'B' with 40 mole percent of 'A' is in equilibrium with its vapour which contain 50 mole percent of A. Assuming that the solution and the vapour behave ideally, calculate the ratio of the vapour pressures of pure A and pure 'B'.

The vapour pressure of water is 12.3.kRa at 300.calculate the vapour pressure of 1 molal solution in it

An aqueous solution is 1 molal in KI. Which change will cause the vapour pressure of the solution to increase

The solution having highest vapour pressure is :(Assume 100% ionisation of electrolytes)

A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased. What happens when equilibrium is restored finally and what will be the final vapour pressure?

A solution containing '30 g' of.non-volatile solute exactly in '90, g' of water has a vapour pressure of '2.8 kPa' at '298 K'. Further, '18 g' of water is then added to the solution and the new vapour pressure becomes '2.9 kPa' at '298K' Calculate: (i) molar mass of the solute (ii) vapour pressure of water at '298 K'.

100 g of liquid 'A' (molar mass '140 g/ mol' ) was dissolved in 1000 g of liquid 'B'. (molar mass 180 g/mol 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.
