Question- A researcher studying the nutritional value of a new candy places a 3.30-gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.89 °C. If the heat capacity of the calorimeter is 43.20 kJ•Kâ€"1, how many nutritional Calories are there per gram of the candy?
