A sample of 25.2 g of a candy bar was burned in a calorimeter. The calorimeter was calibrated to have a heat capacity of 8.72 kcal/ °C. The heat released caused the temperature of the calorimeter to increase 16.7 °C. Calculate the food caloric content of the candy bar in nutritional calories per gram to three significant figures. Recall that 1 nutritional calorie (Cal) = 1 kcal.
