Assume that a single cylinder of an automobile engine has a volume of 617. mL. If the cylinder is full of air (mole fraction of oxygen is 0.2095) at a pressure of 0.954 atm. at a temperature of 70.2 oC., how many grams of C8H18 (octane) can be combusted by this much air assuming complete combustion?
