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

Find the pressure of $5 \ mol$ $Cl_2$ gas filled in a $2 \ L$ vessel at $27 \ ^oC$ temperature. (in $bar$)

Which of the following gases of the same mass exerts the highest pressure at a constant temperature?

Pure hydrogen sulphide is stored in a tank of $100 \, L$ capacity at $20 \, ^oC$ and $2 \, atm$ pressure. The mass of the gas will be ............... $g$.

At temperature $t \, ^oC$,the pressure exerted by $12 \, g$ of an ideal gas in a container of volume $V \, L$ is $1 \, atm$. When the temperature is increased by $10 \, ^oC$ without changing the volume,the pressure increases by $10 \%$. Find the temperature $t$ and volume $V$ in $L$. (Molar mass of the gas = $120 \, g/mol$)

Four vessels of same volume consist of equal moles of four gases $H_2$,$Cl_2$,$N_2$,and $O_2$ separately at the same temperature. The pressure exerted by the gas is maximum for -
