Ethanolisa renewable ritsourceand ethancl. blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The combustion of one mole of ethanol releases 3267 keal of enersy The combustion of one mole of octane, C8H15, releases 1.308103 kcal of energy. How much energy is relessed during the complete combustion of 356 ursm of octane? Assuming the same efficiency, would 356 grams of ethanol provde more, less, or the same amount of enerby as 256 grams af octane?
