Each mole of water has a weight of 18 grams. So the burning of one gallon of gasoline produces 3,914.6 grams of water. This is equal to 8.6 pounds of water, which has a volume of 1.033 gallons. Thus the water vapor put into the atmosphere by burning gasoline is equal to 390 millions of gallons of water per day.
