The deviation of a gas from ideal behavior can be expressed by which of the following?

$A$ $5.75 \ g$ sample of a gas occupies $3.5 \ L$ at $55 \ ^oC$ and $0.940 \ atm$ pressure. What is the molecular weight of the gas?

If the absolute temperature of an ideal gas becomes double and the pressure becomes half,the volume of the gas would be:

The volume of $2.8 \ g$ of $CO$ at $27^{\circ} C$ and $0.821 \ atm$ pressure is (Given: $R = 0.08210 \ L \ atm \ K^{-1} \ mol^{-1}$) (in $L$)

$A$ dry gas occupied $127.4 \, mL$ at $STP$. If the same mass of the gas is collected over water at $27 \, ^\circ C$ and at a total pressure of $725 \, torr$,what volume does it occupy? The vapour pressure of water at $27 \, ^\circ C$ is $25 \, torr$. (Note: $1 \, bar = 750 \, torr$)

$2 \ g$ of $O_2$ at $27 \ ^\circ C$ and $760 \ mm$ of $Hg$ pressure has volume ............. $L$.
