Answer
$8.9\times10^{10}\,L$
Work Step by Step
We find:
$1\,lb= 453.592\, g$
$\implies 3.6\times10^{11}\,lb=3.6\times10^{11}\,lb\times\frac{453.592\,g}{1\,lb}$
$=1.63293\times10^{14}\,g$
$\text{Volume}=\frac{\text{mass}}{\text{density}}=\frac{1.63293\times10^{14}\,g}{1.8302\,g/cm^{3} }=8.9\times10^{13}\,cm^{3}$
$=8.9\times10^{13}\,cm^{3}\times\frac{1\,L}{1000\,cm^{3}}$
$=8.9\times10^{10}\,L$
