Moles, gases and solutions

a$)$ A camping gas cylinder holds $450g$ of pentane, which burns completely in oxygen to form carbon dioxide and water.

$C_5{H}_{12}+8O_{2}5C{O}_2+6H_{2}O$

What is the theoretical volume of steam produced when all the pentane is completely burned? You can assume the molar volume of a gas is $24d{m}^3.$
