The density of oxygen gas at $5 \text{ atm}$ and $127^{\circ} C$ will be (in $\text{ g/L}$)

$A$ vessel contains $3.2 \ g$ of dioxygen gas at $STP$ ($273.15 \ K$ and $1 \ atm$ pressure). The gas is now transferred to another vessel at constant temperature,where pressure becomes one third of the original pressure. The volume of the new vessel in $L$ is $........$ (Given: molar volume at $STP$ is $22.4 \ L$)

Calculate the new pressure of a gas enclosed in a cylinder when it is compressed from $5 \text{ L}$ to $2 \text{ L}$ at an initial pressure of $1 \text{ atm}$ and temperature of $300 \text{ K}$. The final temperature in this process is $500 \text{ K}$. (in $\text{ atm}$)

In order to increase the volume of a gas by $10 \%$,the pressure of the gas should be

$2.9 \, g$ of a gas at $95^{\circ} C$ occupied the same volume as $0.184 \, g$ of dihydrogen at $17^{\circ} C$,at the same pressure. What is the molar mass of the gas?

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