Petrol contains about 84% carbon and 16% hydrogen by weight so a litre weighing 700 grams contains 588 grams of carbon and 112 grams of hydrogen. In the engine it would burn with 2464 grams of oxygen to produce 2156 grams of CO2 and 1008 grams of water (steam), which is normally invisible but can be seen in the exhaust gases from a cold engine.
