A candy sample is completely combusted in a bomb calorimeter. The calorimeter contains 982 g of water, and the measured temperature increase is 2.62°C. What is the fuel value of the candy sample in
q = mass x specific heat x (Tfinal-Tinitial)
q = 982 g x 1 cal/g x 2.62 = approximately 2,572.8 calories (the real kind of calorie). I would round that to 2.57E1 kilocalories. Since the nutritional calorie (the so-called Big calorie) = 1 kcal, the answer is 2.57 Cal.
