Answer
$V=16.2L$
Work Step by Step
We know that
$PV=nRT$
but $n=\frac{m}{M}$ Where $m$ and $M$ are given mass and molar mass respectively
$\implies PV=\frac{mRT}{M}$
This can be rearranged as
$V=\frac{mRT}{PM}$............eq(1)
$P=742 mmHg\times\frac{1atm}{760mmHg}=0.97632atm$
We plug in the known values in eq(1) to obtain:
$V=\frac{28.8\times 0.08206\times 295.15}{0.97632\times 44.0095}=16.2L$
