Ethanol, C2H6O, is most often blended with gasoline - usually as a 10 per cent 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 octane, C8H18, is 1.308×103 kcal/mol. How much energy is released during the complete combustion of379 grams of octane ?

 kcal

Assuming the same efficiency, would 379 grams of ethanol provide more, less, or the same amount of energy as 379 grams ofoctane? _________morelessthe same amount
