Hi There I didn’t pay much attention in sciences classes I am afraid.
But some one should be able to help me out.
I try to live as consciously as possible and deal with the environment and CO2 emissions. But one thing always stays with me: The volume of CO2.
People always talk about kg CO2 per… For example: diving 5 km in a average car would emit 1kg of CO2. I drive a Toyota Aygo, so a little less then average, but lets say could drive around 20km on 1 litre of fuel. That would mean I’ll use around 0,25 litre for 5 km.
Typical E10 fuel weighs around 0,85kg per litre. That should mean I used around 212 grams of fuel to produce 1kg of CO2. That math doesn’t count up for me… Where does the other 788 grams come from?

CO2 forms when fuel reacts with oxygen from the atmosphere. Fuel mostly consists of hydrocarbons which, in turn, consist mostly of carbon and hydrogen. When it burns, hydrogen forms H2O (water) and carbon forms CO2.
However, 1 kg of CO2 from 0.2 kg of fuel still seems impossible, you data must be wrong somewhere. Atomic mass of carbon is 12, oxygen is 16, so CO2 is 44. So, even pure carbon would only produce 3.666(6) times its weight after it’s burned, for any other fuel it should be less.
