$A$ gas occupies $10 \ L$ at $0 \ ^{\circ}C$ and $2 \ atm$ pressure. At what temperature will the pressure in the container be $2.5 \ atm$,assuming the volume remains constant (in $^{\circ}C$)?

$A$ $5.75 \ g$ sample of a gas occupies $3.5 \ L$ at $55 \ ^oC$ and $0.940 \ atm$ pressure. What is the molecular weight of the gas?

At constant temperature,in a given mass of an ideal gas,

$A$ 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 $22.4 \ L$)

In an experiment during the analysis of a carbon compound,$145 \ L$ of $H_2$ was collected at $760 \ mm \ Hg$ pressure and $27 \ ^oC$ temperature. The mass of $H_2$ is nearly $....... \ g$.

$A$ sample of gas occupies $100 \ mL$ at $27 \ ^oC$ and $740 \ mm$ pressure. What will be the temperature of the gas in $^oC$ if its volume is changed to $80 \ mL$ at $740 \ mm$ pressure?
