139071 A cylinder of volume $V$ contains a mixture of 8 $\mathrm{g}$ of oxygen, $14 \mathrm{~g}$ of nitrogen and $22 \mathrm{~g}$ of carbon dioxide at absolute temperature $T$. The pressure of the gas mixture will be ( $R$ is universal gas constant)

139072 Two vessels separately contain two ideal gases $A$ and $B$ at the same temperature. The pressure of is twice that of $B$. Under these conditions, the density of $A$ is found to be one and half times the density of $B$, the ratio of molecular weights of $A$ and $B$ is

139073 A vessel of volume $8 \times 10^{-3} \mathrm{~m}^{3}$ contains an ideal gas at $300 \mathrm{~K}$ and $200 \mathrm{kPa}$. The gas is allowed to leak till the pressure falls to $125 \mathrm{kPa}$. The amount of gas leaked is (assuming temperature remains constant)
