A birthday candle is 2.5 inches long and 0.75 cm in diameter.It’s made of paraffin wax, which is a mixture of varioushydrocarbons, but for the sake of argument we’ll assume it’s allC31H64, since that’s the major component. Its density is 0.90 g/cm3paraffin. If air is 20.95% O2 by volume, and the density of O2 is1.43 g/L, then how many liters of air will the candle consume if itcompletely burns up? (Note that paraffin combines with oxygen tomake carbon dioxide and water.)
