If $P$ is pressure and $\rho$ is density of a gas,then $P$ and $\rho$ are related as

The volume of a gas at $0^{\circ} C$ is $2 \ dm^3$. What is its volume if the temperature is decreased by $272^{\circ} C$?

The $S.I.$ unit of the gas constant $R$ is:

What is the density of carbon monoxide at $STP$ in $g \, L^{-1}$?

In the ideal gas equation,the gas constant $R$ has the dimensions of

At $740 \ torr$ pressure,the volume of $N_2$ gas is $800 \ mL$. If the volume becomes $540 \ mL$ at constant temperature,calculate the pressure of the gas. (in $torr$)
