The volume occupied by $1.8 \; g$ of water vapour at $374^{\circ} C$ and $1 \; bar$ pressure will be $....... \; L$ : [Use $R=0.083 \; bar \; L \; K^{-1} \; mol^{-1}$]

At temperature $T$,$1$ mole of $O_2$ gas (molar mass $32 \ g/mol$) is present in a container,exerting a pressure $P$. If $1$ mole of $He$ gas (molar mass $4 \ g/mol$) is placed in an identical container at temperature $2T$,what will be the pressure exerted by the $He$ gas?

If $500 \ mL$ of gas $A$ at $1000 \ torr$ and $1000 \ mL$ of gas $B$ at $800 \ torr$ are taken in a $2 \ L$ container,the final pressure is .......... $torr$.

For an ideal gas,the number of moles per litre in terms of its pressure $P$,gas constant $R$,and temperature $T$ is:

At what temperature in $K$ will $28 \ g$ of $N_2$ gas occupy a volume of $10.0 \ L$ at $2.46 \ atm$ pressure?

The correct value of the gas constant $R$ is close to
