image text in transcribed

Find: 1. Determine the theoretical stoichiometric ratio (based on mass) between the air and the fuel.

2. How much CO2 ia released per kilometer (in grams CO2 per kilometer) when we assume that the car consumes 6.2 liters of petrol per 100 km (density of petrol= 0.75 kg/liter)?

3. In reality, the ratio (from 1) used is less then the calculated ratio, how does this affect the emissions from the combustion process?

C7H13+10,25O2+38,54N27CO2+6,5H2O+38,54N2
