An aqueous solution of methanol in water has vapour pressure:

What is the vapour pressure of a solution of glucose which has an osmotic pressure of 3 atmospheres at $$20^C?$$ The vapour pressure of water at $$20^oC$$ is $$17.39 mm$$. Consider the density of solution equal to that of the solvent.

At $$25^oC$$, the vapour pressure of pure benzene is 100 torr, while that of pure ethyl alcohol is 44 torr. Assuming ideal behaviour, calculate the vapour pressure at $$25^oC$$ of a solution which contains 10 g of each substance.

Which of the following do not pertain to the postulates of kinetic theory of gases?

Plot of Maxwell's distribution of velocities is given below:
which of following is correct?

Which of the following property indicates weak intermolecular forces of attraction in liquid?

At $$27^{\circ}C$$ a sample of ammonia gas exerts a pressure of $$5.3\ atm$$. What is the pressure when the volume of the gas is reduced to one-tenth of the original value at the same temperature?

A vessel of volume $$5$$ liter contains $$1.4\ g$$ of nitrogen at a temperature $$1800\ K$$. The pressure of the gas if $$30$$% of its molecules are dissociated into atoms at this temperature is :

The temperature, at which the density of $$O_{2}$$ at $$1\ atm$$, is the same as that of $$CH_{4}$$ at S.T.P is:

Equal weights of two gases of molecular weight $$4$$ and $$40$$ are mixed. The pressure of the mixture is $$1.1$$ atm. The partial pressure of the light gas in this mixture is :
