The density of $$O_{2}$$ is 16 kg/m$$^3$$ at NTP .At what temperature its density will be 14 kg/m$$^3$$ ? consider that the pressure remains constant.

Two liquids, A and B, form an ideal solution. At the specified temperature, the vapour pressure of pure A is 200 mm Hg while that of pure B is 75 mm Hg. If the vapour over the mixture consists of 50 mol percent A, what is the mole percent A in the liquid?

The no. of moles per liter in the equation $$PV=nRT$$ is expressed by:

The relative decrease in vapour pressure of an aqua solution containing 2 moles of $$4NaCl$$ in 3 moles of $${H}2_{O}$$ is 0.50. On reaction with $$AgNO_3$$ this solution will form:

A gas volume 100 cc. is kept in a vessel at pressure $$10^4$$ atm maintained at temperature $$24^0C$$. If now the pressure is increased to $$10^5$$ atm, keeping the temperature constant, then the volume of the gas becomes:

A glass tube of volume 112ml containing a gas is partially evacuated till the pressure in it drops to $$3.8\times { 10 }^{ -5 }$$ torr at 0 degree C.The number of molecules of the gas remaining in the tube?

If $$P^o$$ and $$P^s$$ are the vapour pressure of the solvent and solution respectively. $$n_ 1$$ and $$n_2$$ are the mole fraction of the solvent and solute respectively, then?

The density of $$O_2$$ is 16 kg/m$$^3$$ at NTP. At what temperature its density will be 19? consider that the pressure remains constant.

An ideal gas filled at pressure of $$2 atm$$ and temp of $$300 K$$, in a balloon is kept in vacuum with in a large container wall of balloon is punctured then container temperature:
