The combustion of fuel in your car engine requires oxygen gas, which is supplied as air (21% oxygen molecules) into the engine. consider a car that is using 100% ethanol, c2h5oh, as fuel. if your engine intakes 4.73 l of air per minute at 1.00 atm and 25ºc, what is the maximum volume of ethanol (0.789 g/ml) that can be burned per minute? hint: you can ignore the "per minute" information because both the ethanol and air are being quantified per minute. enter your answer to three significant figures in units of ml.
