[Review Topics] [References] Use the References to access important values if needed for this question. Ethanol, C2H,O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol. The heat of combustion of hexane, C,H14, is 995.0 kcal/mol. How much energy is released during the complete combustion of 479 grams of hexane ? kcal Assuming the same efficiency, would 479 grams of ethanol provide more, less, or the same amount of energy as 479 grams of hexane?
