Question

The molar volume of one mole of gas at one atmospheric pressure and ${273}^o$ $C$ temperature is:

• A. 22.4 $L$
• B. 11.2 $L$
• C. 44.8 $L$
• D. 33.6 $L$

Answer 1

The correct option is C 44.8 $L$

1 mole of gas at 1 atm pressure is at $273{}^{o}C$.

Temperature $\left(K\right)=273+273=546K$

$PV=nRT$

$n=1,T=546K,P=1atm,R=0.0821$

$\therefore V=\frac{1\times 0.0821\times 546}{1}=44.8litres$
