A 22 g dried sample of food is placed in an aluminum bomb calorimeter and burned completely. The device consists of an aluminum chamber (0.50 kg) containing the sample, a surrounding water bath (2.00 kg), and an aluminum cup (0.60 kg) holding the water. A thermometer in the water shows that the calorimeter changes temperature from 20°C to 34°C; how many kilocalories did the food make available? Neglect the mass of the ash.
