Benzoic acid completely dimerises in benzene. What will be the vapour pressure of a solution containing 61g of benzoic acid per 500g benzene when the vapour pressure of pure benzene at the temperature of experiment is 66.6 Torr?

Benzoic acid under goes dimenization in benzene solution, the Van't Hoff factor related to the degree of associatioin 'x' of the acid as.

Solution of two volatile liquids A and B obey Roalt's law. At certain temperature, it is found that when the toal pressure above a solution is 0.53 bar. The mol fraction. A in the vapour is 0.45 & other liquid is 0.65. What are the vapour pressures of the two pure liquids at the given temperature?

The partial pressure of ethane over a solution containing 6.56xx10^-3 g of ethane is 1 bar. If the solution contains 5.00xx10^-2 g of ethane, then what shall be the partial pressure of the gas?

Heptane and octane form an ideal solution. At 373 K, the vapour pressures of the two liquid components are 105.2 kPa and 46.8 kPa respectively. What will be the vapour pressure of a mixture of 26.0 g of heptane and 35 g of octane?

100 g of liquid A (molar mass 140 g mol^-1) was dissolved in 1000g 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.

A solution containing 30g of non-volatile solute exactly in 90g 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 298 K. Calculate: molar mass of the solute

2.5gm ethanoic acid (CH_3COOH) is dissolved in 75g benzene. Calculate the molality of the solution. (molecular mass of CH_3COOH = 60u )

Benzene and toluene form ideal solution over the entire range of composition. The vapour pressure of pure benzene and toulene 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.

Show that for dimerisation of benzoic acid in benzene solution, degree of association, = 2(1-i) where I = Van't Hoff factor.

Heptane and Octane form an ideal solution at 373K the vapour pressure of the pure liquids at this temperature are 105.2 kPa respectively. If the solution contains 25g of heptane and 28.5g octane, calculate Vapour pressure exerted by solution.
