20 cm320\,\mathrm{cm^{3}}20cm3 of propane is mixed with 150 cm3150\,\mathrm{cm^{3}}150cm3 of oxygen and ignited. The propane burns completely.

C3H8(g)+5O2(g)→3CO2(g)+4H2O(l)\mathrm{C_{3}H_{8}(g) + 5O_{2}(g) \rightarrow 3CO_{2}(g) + 4H_{2}O(l)}C3​H8​(g)+5O2​(g)→3CO2​(g)+4H2​O(l)

The mixture is cooled to the starting temperature and pressure, so the water is a liquid.

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