Answer
$13L$
Work Step by Step
We know that
$PV=nRT$
$\implies n=\frac{PV}{RT}$
$n=\frac{101\times 10^3\times 3.7}{8.314\times 87}$
$n=5.16\times 10^{-3}moles$
Now we can find the final volume as
$V=\frac{nRT}{P}$
We plug in the known values to obtain:
$V=\frac{5.16\times 10^{-3}(8.314)(297)}{101\times 10^3}$
$V=13L$
