At $\mathrm{STP} 5.6 \mathrm{litre}$ of a gas weigh $60 \mathrm{g}$. The vapour density of gas is:

At 100^oC and 1 atm, if the density of liquid water is 1 g cm^–3 and that of water vapour is 0.0006 g cm^–3, then the volume occupied by water molecules in 1 litre of steam at that temperature is

A gas is found to have formula${\left[\mathrm{C}\mathrm{O}\right]}_{\mathrm{x}}$. Its vapour density is 70, the $x$ is

The vapour density of a gas is $11.2$. The volume occupied by $11.2 \mathrm{g}$ of the gas at $\mathrm{N}.\mathrm{T}.\mathrm{P}.$ is :

The vapour density of ozone will be :
