During the combustion of 5.00 g of ethanol (C2H5OH) 35.5 kcal of energy are released. How many grams of ethanol must be burned to release 450. kcal of energy? Report your answer to 3 sig figs. Do not include units and do not put your answer in scientific notation. (hint: there are several ways to correctly do this problem. Dimensional analysis is one of them. But in this case there's an easier way, if you can think of it. Remember,
