Use the References to access important values i Ethanol 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 2-methylhexane is 1.150x103 kcal/mol. How much energy is released during the complete combustion of 351 grams of 2-methylhexane? kcal Assuming the same efficiency, would 351 grams of ethanol provide more, less, or the same amount of energy as 351 grams of 2-methylhexane?
