In the gas equation $PV = nRT$,the universal gas constant $R$ depends on:

$A$ gas occupies a volume of $300 \, cc$ at $27 \, ^\circ C$ and $620 \, mm$ pressure. The volume of gas at $47 \, ^\circ C$ and $640 \, mm$ pressure is......$cc$

The density of neon will be highest at

$A$ closed container is maintained at a constant temperature. It is first evacuated and then an ideal gas is continuously introduced into it. What will be the pressure of the gas inside the container?

$16 \, g$ of oxygen and $3 \, g$ of hydrogen are mixed and kept at $760 \, mm$ pressure and $0 \, ^oC$. The total volume occupied by the mixture will be nearly

The gram molecular volume of an ideal gas at $STP$ is $22400 \ cm^{3}$. However,for oxygen gas,the question asks for the volume. Given the options provided,the correct value for $1 \ \text{mole}$ of any ideal gas at $STP$ is $22400 \ cm^{3}$. Please note that the provided solution in the prompt was incorrect. (in $cm^{3}$)
