Question

The pressure at which one mole of a gas at $0^{o}C$ occupies a volume of 1 litre is:

• A. $1$ $atm$
• B. $760$ $atm$
• C. $22.4$ $atm$
• D. $273$ $atm$

Answer 1

The correct option is C $22.4$ $atm$

From ideal gas equation, $PV=nRT$,
we put $V=1$ $L$, $n=1$ $mole$, $R=0.0821$ $L$ $atmmo{l}^{-1}{K}^{-1}$ and $T=273$ $K$,
we get $P=22.4$ $atm$.
