Number of moles propto (1/ textMolecular mass) Molecular mass of CO2 = 44, N2= 28, CH4= 16, HCl=36.5 CO2 will have least volume, as no. of moles is directly proportional to volume at constant P and T.

Q. Which of the following gases will have least volume if $10 g$ of each gas is taken at same temperature and pressure?

$C O_{2}$

$N_{2}$

$C H_{4}$

$H Cl$

Number of moles $\propto \frac{1}{Molecular mass}$
Molecular mass of $C O_{2} = 44, N_{2} = 28, C H_{4} = 16$ ,
$H Cl = 36.5$
$C O_{2}$ will have least volume, as no. of moles is directly proportional to volume at constant $P$ and $T$ .
