Ideal Gas Equation

Under what conditions can ideal gases be liquefied? Give reasons to support your answer.

The mass of $256 \mathrm{mL}$ of a triatomic elemental gas at $27°\mathrm{C}$ and $4 \mathrm{atm}$ is $2 \mathrm{g}$. Calculate the weight of one atom.

The vapour density of hydrogen peroxide is equal to molecular weight of ${\mathrm{NH}}_3$.

Equal masses of the three gases, ammonia, nitrogen dioxide and methane are taken in three cylinders having a volume ratio of $2 : 5 : 7$ at a certain temperature. Draw a comparison of the pressures exerted by those gases.

The value of the universal gas constant $\mathrm{R}$ value in calorie per degree temperature per mol is approximately
