What you have to do is convert units. DO you have any expirience with this?

1. Knowing rules of combustion...
C8H18 + O2 -> CO2 + H2O
2. Balance the equation
2C8H18 + 25O2 -> 16CO2 + 18H2O

...
After reading more I found out they give the amt of CO2, silly me.

Ferredoxin4 · Answer

just use conversion units and solve.

5.25 L C8H18 * (1 gallon/3.79 L) * (8.62 lb CO2/1 gallon C8H18) * (1 kg/2.20 lb) = your answer
