1) A researcher studying the nutritional value of a new candy places a 6.60-gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.37 °C. If the heat capacity of the calorimeter is 41.20 kJ·Kâ1, how many nutritional Calories are there per gram of the candy?
2) If the heat of combustion for a specific compound is -1310.0 kJ/mol and its molar mass is 82.49 g/mol, how many grams of this compound must you burn to release 733.90 kJ of heat?
