Balanced equation:
2 C8H18 + 25 O2--> 16CO2 + 18H2O
According to my chemistry book 1 gal of C8H18 combust to produce 9.3 kg CO2.
Our trip to Virgina used 44 gals of gas (87 octane) so...
44 gals x .87 octane = 38. 28 gals octane x 9.3kg CO2 = 356.004 kg CO2.
This seems to make sense since 44 gallons of octane weighs about 124kg. Octane weights 5.85 lbs per gal. 5.85 x 44 gal = 257.4 lbs (116.75 kg).
So... 356 x 2 = 712 kg CO2 total produced for round trip.
