At $${ 20 }^{ 0 }C$$, the vapour pressure of diethyl either is 44mm. When 6.4 g. of a non-volatile solute is dissolved in 50g. of either, the vapour pressure falls to 410mm. The Molecular weight of the solute is:

Equal masses of $${ SO }_{ 2, }{ CH }_{ 4 }$$ and $${ CH }_{ 4 }$$ are mixed in empty container at 298 K, when total pressure is 2.1 atm. The partial pressure of $$O_2$$ in the mixture is:

18 g glucose is added to 178.2 g of water the vapour pressure of water for this aqueous solution at $${ 100 }^{ 0 }C$$ is:

Which of the following curve does not represent Gay-lussac's law?

Which of the liquids in each of the following pairs has a higher vapour pressure?

Vapour pressure of $${ CCI }_{ 4 }$$ at $${ 24 }^{ o }C$$ is $$143 mmHg 0.05$$g of the non-volatile solute (mol.wt.=65) is dissolved in $$100 ml { CCI }_{ 4 }$$. Find the vapour pressure of the solution (Density of $${ CCI }_{ 4 }$$=$$1.58 g/{ cm }^{ 2 }$$)

The vapour pressure of water at $$20$$ is 17.5 mm Hg. If 18 g of glucose $${ C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 }$$ is added to 178.2 g water $$20$$ , the vapour pressure of the resulting solution will be:

The vapour pressure of o-nitrophenol at any given temperature is predicted to be: 

Equal weights of $$HF$$, $$HCl$$ ,$$HBr$$ , and $$HI$$ $${at\ 87}^{0}C$$ and $$750\ mm$$ $$Hg$$ pressure are taken. The correct sequence of these gases in the increasing order of their volume is ?

An open vessel at $$300\ K$$ is heated till $$\dfrac { 2 }{ 5 } $$ of the air in it expelled. Assuming that the volume of the vessel remains constant, the temperature to which the vessel is heated, is
