Both statement-$I$ and statement-$II$ are correct

(A) Statement-$I$ is correct: The compressibility factor $Z$ is defined as $Z = \frac{V_{m, \text{real}}}{V_{m, \text{ideal}}}$,which represents the ratio of the molar volume of a real gas to that of an ideal gas at the same temperature and pressure.Statement-$II$ is correct: The root mean square $(RMS)$ velocity of a gas is given by the formula $v_{rms} = \sqrt{\frac{3RT}{M}}$. Since $R$ and $M$ are constants for a given gas,$v_{rms} \propto \sqrt{T}$.Therefore,both statements are correct.

Two statements are given below.
Statement-$I$: The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.
Statement-$II$: The $RMS$ velocity of a gas is directly proportional to the square root of $T(K)$.
The correct answer is

At $298 \ K$,a flask '$A$' of unknown volume $(V)$ contains oxygen at $5 \ atm$. Another flask '$B$' of volume $2 \ L$ contains helium at $3 \ atm$. Two flasks are connected together by a small tube of zero volume. After the two gases are completely mixed,if the resulting mixture is found to have the mole fraction of oxygen as $0.2$,the volume of flask '$A$' (in $L$) is (Assume oxygen and helium as ideal gases)
