Ethanol, C,H,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 2-methylheptane, C3H18, is 1.306×10³ kcal/mol. How much energy is released during the complete
combustion of 482 grams of 2-methylheptane ?
kcal
Assuming the same efficiency, would 482 grams of ethanol provide more, less, or the same amount of energy as 482 grams of 2-
methylheptane v
