Considering the given equation C3H8(g) + 5O2(g) = 3CO2(g) + 4H2O(g) in which Propane and oxygen reacts Compute the volume of CO2 and water vapour produced and the volume of oxygen remaining, when 20.0 dm3 of propane reacts with 120.0 dm3 of oxygen. All gas volumes are measured at the same temperature and pressure.
