Rectified spirit is a mixture of alcohol and water which behaves like pure liquid and boils at constant temperature. Calculate the vapour pressure of 10% aqueous solution of glucose (molecules mass 180) at 303 K. The vapour pressure of pure water at 303 K is 31.8 mm.

Rectified spirit is a mixture of alcohol and water which behaves like pure liquid and boils at constant temperature. What name can be given to such a mixture ?

The vapour pressure of a 10% aqueous solution of a non volatile substance at 373K is 740 mm of Hg. Calculate the molecular mass of the solute.

Vapour pressure of an aqueous of solution of glucose is 750mm Hg at 373k. Calculate the molality and mole fraction of the solution.

Vapour pressure of pure water at 298 K is 23.8mmHg. 50g of urea is dissolved in 850g of water. Calculate the vapour pressure of water for this solution and its relative lowering.

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.

What mass of solute ("molar mass=60 g mol"^(-1)) should be dissolved in 180 g water to reduce the vapour pressure to 4/5 th of pure water :

The amount of solute (mol. Mass=60) that must be added to 180 g of water so that the vapour pressure of water is lowered by 10% is

The vapour pressure of water is 92.5 mm at 300 K. The V.P. of 1 molal aqueous solution of non volatile non electrolyte solute is
