Question 33

Propane burns completely in oxygen.

$C3H8+5O2→3CO2+4H2O\text{C}_3\text{H}_8 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}$

20 cm³ of propane is burned in 120 cm³ of oxygen. The gases left at the end are cooled to room temperature and pressure, so the water is a liquid.

What is the total volume of gas left at the end?
