Ethanol is a renewable fuel made from biomass (most commonly corn in the US). The fuel we buy at gas stations typically contains 10% ethanol and 90% gasoline by volume. The chemical formula for ethanol is C2H60 and the atomic weight of each element is as follows: carbon 12 amu; hydrogen 1 amu; oxygen 16 amu. Ethanol has a density of 789 kg/m3 and there are 1000 liters in one cubic meter. How many moles of ethanol are in one gallon of fuel and how much would that much ethanol weigh (in USCS units)
