Ideal Gas Equation

At the value of the density of a fixed mass of an ideal gas divided by its pressure is At this ratio is:

1.		2.
3.		4.

In the given diagram, what is the relation between pressure and ? 

1.		2.
3.	cannot be predicted	4.

Two vessels separately contain two ideal gases and at the same temperature, the pressure of being twice that of Under such conditions, the density of is found to be times the density of The ratio of molecular weight of and is:

1.		2.
3.		4.

A given sample of an ideal gas occupies a volume at a pressure and absolute temperature . The mass of each molecule of the gas is . Which of the following gives the density of the gas?

1.		2.
3.		4.

An ideal gas equation can be written as where and are respectively:

1.	mass density, the mass of the gas.
2.	number density, molar mass.
3.	mass density, molar mass.
4.	number density, the mass of the gas.

The volume occupied by the molecules contained in water at STP, if the molecular forces vanish away, is:

1.		2.
3.		4.
