a fire nozzle weighs approximately  ten to fifteen pounds.
Thus, you would have eight CO2 molecules per octane molecule burned--or eight moles of CO2 per mole of octane burned. The weight of CO2 is 44 grams per mole (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms). Burning one mole of octane (114 grams), therefore, would produce eight moles of CO2, with a weight of 352 grams (8 x 44). Thus, the weight ratio of CO2 produced per octane molecule burned is 352/114, or roughly 3 to 1. Actual weight ratios will of course vary, since gasoline is not purely octane. In general, however, when you burn carbon fuels they are in reduced form, that is, the carbons in the molecules are attached mostly to hydrogen atoms. When they are burned, the carbon becomes oxidized (literally, combined with oxygen) to make CO 2.
