To which of the following the Dalton's law of partial pressures is not applicable?

A $$10\ L$$ flask contains a gaseous mixture of $$CO$$ and $$CO_{2}$$ at a total pressure of $$2\ atm$$ and $$298\ K$$. If $$0.20\ mole$$ of $$CO$$ is present, find its partial pressure.

If $$4\ moles$$ of an ideal gas at $$300\ K$$ occupy volume of $$89.6\ L$$, then pressure of the gas will be :

A gas occupies a volume of $$300\ cm^{3}$$ at $$27^{\circ}C$$ and $$620\ mm$$ pressure. The volume of gas at $$47^{\circ}C$$ and $$640\ mm$$ pressure is:

A closed container contains equal number of moles of two gases $$X$$ and $$Y$$ at a total pressure of $$710\ mm$$ of $$Hg$$. If gas $$X$$ is removed from the mixture, the pressure will :

What will be the volume of $$2.8\ g$$ of carbon monoxide at $$27^{\circ}C$$ and $$0.821$$ atmospheric pressure?

$$34.05\ mL$$ of phosphorus vapours weight $$0.0625\ g$$ at $$546^{\circ}C$$ and $$0.1\ bar$$ pressure. What is the molar mass of phosphorus?

What will be the pressure of the gas mixture of $$3.2\ g$$ methane and $$4.4\ g$$ carbon dioxide contained in at $$9\ dm^{3}$$ flask at $$27^{\circ}C$$?

Density of a gas is found to be $$5.46\ g/ dm^{3}$$ at $$27^{\circ}C$$ and $$2\ bar$$ pressure. What will be its density at STP?

The volume occupied by $$88\ g$$ of $$CO_2$$ at $$30^{\circ}C$$  and $$1\ bar$$ pressure will be:
