A $$4.40\ g$$ piece of solid $$CO_{2}$$ is allowed to subline in a ballon. The final volume of the ballon is $$1.00\ L$$ at $$300\ K$$. What is the pressure of gas?

The vapour pressure of water at $$20^{o}C$$ is $$17.54mm Hg$$. Then the vapour pressure of the water in the apparatus is lowered, decreasing the volume of the gas above the liquid to one half of its initial volume (temp. constant) is:

For the equilibrium ,$${ 2SO }_{ 3 }(g)\rightleftharpoons 2{ SO }_{ 2 }(g)+{ O }_{ 2 }(g)$$; the partial pressure of $${ SO }_{ 3 }$$, $${ SO }_{ 2 }$$ and $${ O }_{ 2 }$$ gases at $$650 K$$ are respectively $$0.2 bar,0.6 bar$$ and $$0.4 bar$$. If the moles of both oxides of sulphur are so adjusted as equal, what will be the partial pressure of $${ O }_{ 2 }$$?

If $$P, V, M, T$$ and $$R$$ are pressure, volume, molar mass, temperature and gas constant respectively, then for an ideal gas, the density is given by:

The volume of $$2.8\ g$$ of carbon monoxide at $$27^{o}C$$ and $$0.821 atm$$ pressure is:

$$3$$ moles of $$P$$ and $$2$$ moles of $$Q$$ are mixed, what will be their total vapour pressure in the solution if their partial vapour pressures are $$80$$ and $$60$$ respectively?

Combination that does not obey Dalton's law:
$$A=CO$$
$$B=Cl_{2}$$
$$C=F_{2}$$
$$D=Xe$$

$$4$$ moles $$CO, 5$$ mole $$N_{2}$$ and $$2$$ mole $$C_{2}H_{4}$$ are placed in a $$5$$ litre at $$27^{o}C$$. The ratio of kinetic energy per molecular of $$CO_{2}$$, $$He$$ and $$NH_{3}$$ is:

Which of the following expression is true regarding gas laws? 

A gas at a pressure of $$5.0$$ bar is heated from $$0^{o}$$ to $$546^{o}C$$ and is simultaneously compressed to one-third of its original volume. Hence, final pressure is:
