A researcher studying the nutritional value of a new candy places a 3.40 g sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.86 ∘C. If the heat capacity of the calorimeter is 33.50 kJ⋅K−1, how many nutritional Calories are there per gram of the candy?
