If $2$ moles of an ideal gas at $546 \ K$ has a volume of $44.8 \ L$,then what will be its pressure (in $atm$)? $(R=0.082 \ L \ atm \ K^{-1} \ mol^{-1})$

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 $L$)

An open vessel at $27\,^{\circ}C$ is heated until $3/5$ of the air in it has been expelled. Assuming the pressure remains constant,what is the final temperature of the vessel in $^{\circ}C$?

$A$ certain sample of gas has a volume of $0.2 \ L$ measured at $1 \ atm$ pressure and $0 \ ^oC$. At the same pressure but at $273 \ ^oC$,its volume will be ................ $L$.

At what temperature does the volume of a gas become theoretically zero?

The correct value of the gas constant $R$ is close to
