Answer
$V=38L$
Work Step by Step
The equation $PV=nRT$ can be re-arranged as:
$V=\frac{nRT}{P}$..........(1)
Now, we convert the temperature to Kelvin: $T=C^{\circ}+20=77+273=350K$
Next, we find the number of moles $n$:
$n=\frac{mass}{M_r}=\frac{300g}{17\frac{g}{mol}}=17.64$
Substituting the values into (1), we get
$V=\frac{(17.64)(8.314)(350)}{1.35\times10^6}$
$V=0.038m^3$
$V=0.038\times1000=38L$
