Molar gas volume

A student burns 40 cm³ of propane, C₃H₈, in excess oxygen in a closed container. The equation is:

$\text{C}_3\text{H}_8(g) + 5\text{O}_2(g) \rightarrow 3\text{CO}_2(g) + 4\text{H}_2\text{O}(l)$.

All water formed condenses to liquid. What is the total volume of gas in the container at room temperature after the reaction?
