Solution

Given information
$320 g$ of sulfur dioxide $({SO}_{2})$
S.T.P
S.T.P indicates standard temperature and pressure
At S.T.P, one mole of a gas has a volume of $22.4 L$ .
Calculation of molecular weight of ${SO}_{2}$
Molecular weight of ${SO}_{2}$
$=S + 2 O = (32 + 2 \times 16) g = 64 g$
Calculation of volume occupied by ${SO}_{2}$ at S.T.P
Since, $64 g$ of ${SO}_{2}$ occupies $22.4 L$ volume at S.T.P.
Therefore, $320 g$ of ${SO}_{2}$ will occupy $\frac{22.4}{64} \times 320 =112L$ volume at S.T.P.
Hence, the volume of $320 g$ of ${SO}_{2}$ at S.T.P. is $112 L$ .
