Zero as you can not make a gallon of gasoline from water.
Bio Diesel is made from soy beans. Ethanol is made from corn.
Currently a bushel of corn produces about 2.8 gallons of ethanol. With better varieties that figure will increase to 3 gallons. In the near future, the corn distillate will be processed again, yielding some more ethanol.
I AM NOT SURE ABOUT HOW MUCH SUGAR CANE IT TAKES, BUT IT TAKES A 5X7 AREA OF CORN TO PRODUCE 1 GAL OF ETHANOL.
Assuming the dry-milling method of ethanol production (the most common), one 56-pound bushel of corn makes 2.7 gallons of fuel ethanol and 17.4 pounds of dried distillers' grain. This means that 69% of the corn went into the ethanol.
it takes 1.5 gallons of fossil fuel to produce 1 gallon of ethanol.
For every gallon of gas containing 10% ethanol (referred to as E10 gas), it will contain 1/10th gallon of ethanol (about 12 ounces by volume). Ethanol is primarily used to oxygenate the gas and replace the chemical MBTE, which pollutes groundwater. HOWEVER, since most ethanol in the US comes from corn, it is important to note that using ethanol in gasoline causes GREATER pollution than just gasoline alone. This is because it actually takes more energy to produce corn based ethanol than is extracted from it. Until better technologies for ethanol production are available (e.g. algae), it is best for the environment to avoid gas containing ethanol if possible (some states mandate it).
As of 2011, approximately 45% of US corn production is being used for ethanol production.

Around 6 lbs. Depends on temperature and elevation.
Ethanol was almost certainly originally discovered through the accidental fermentation of improperly stored fruit or grain. Corn (maize) was unknown to Europeans until around the 15th century, but it was obviously a type of grain, and everybody knew by then you could make ethanol out of grain, so "corn ethanol" wasn't really "discovered" so much as "something everyone assumed to be true turned out to actually be true."
Gasoline enriched with ethanol contains more oxygen - so it burns cleaner and much faster than regular gasoline. Which means it increase the power of your car.
The density of ethanol is 0.789 g/cm3, or 0.789 kg per liter.There are 3.7854 liters per gallon, so 1 gallon of ethanol weighs 2.987 kg.There are 2.2046 lbs per kilogram, so 1 gallon of ethanol weighs 6.584 lbs.Compare that with the weight of 1 gallon of water: 8.3454 lbs
