There are two main units used to describe heat, the calorie and the Joule. The conversion between them is 1 calorie = 4.184 J. A food calorie is equal to 1000 calories of heat or 1 kcal. So if you have a strip of bacon containing 22.0 g of fat and it takes 9 kcal/g of energy( heat) to digest fat, how many kJ of energy have you used? Express your answer to 3 significant figures.
