The initial volume of a gas cylinder is $750.0 \ mL$. If the pressure of gas inside the cylinder changes from $840.0 \ mm \ Hg$ to $360.0 \ mm \ Hg$,what will be the final volume of the gas (in $L$)?

The gas equation $PV = nRT$ is applicable for which of the following conditions?

Which of the following equations does $NOT$ represent Charles's law for a given mass of gas at constant pressure?

Which of the following laws gives the relation between volume and temperature?

Which one of the following graphs is not correct for an ideal gas?
$d =$ Density,$P =$ Pressure,$T =$ Temperature

$A$ glass vessel weighs $50.0 \, g$ when empty. When filled with a liquid of density $0.98 \, g \cdot mL^{-1}$,it weighs $148.0 \, g$. When filled with an ideal gas at $760 \, mm$ of $Hg$ pressure and $300 \, K$ temperature,it weighs $50.5 \, g$. Calculate the molar mass of the gas in $u$.
