The pressure exerted by $6.0 \ g$ of methane gas in a $0.03 \ m^3$ vessel at $129^{\circ} C$ is $........ \ Pa$ (Atomic masses : $C = 12.01, H = 1.01$ and $R = 8.314 \ J K^{-1} mol^{-1}$)

Assuming ideal gas behavior,what is the number of moles of $0.224 \ L$ of hydrogen gas at $STP$ $(273 \ K, 1 \ atm)$?

$n$ moles of an ideal gas at temperature $T$ (in kelvin) occupy $V \ L$ of volume, exerting a pressure of $P$ atmospheres. What is the concentration (in $mol / L$)?

If $20 \ cm^3$ of gas at $1 \ atm$ is expanded to $50 \ cm^3$ at constant $T$,what is the final pressure?

$A$ 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......$cc$

On a ship sailing in the Pacific Ocean where the temperature is $23.4^{\circ} C$,a balloon is filled with $2 \ L$ of air. What will be the volume of the balloon when the ship reaches the Indian Ocean,where the temperature is $26.1^{\circ} C$ (in $L$)?
