A sample of octane (C8H18) that has a mass of 0. 750 g is burned in a bomb calorimeter. As a result, the temperature of the calorimeter increases from 21. 0°C to 41. 0°C. The specific heat of the calorimeter is 1. 50 J/(g • °C), and its mass is 1. 00 kg. How much heat is released during the combustion of this sample? Use q equals m C subscript p Delta T. 22. 5 kJ 30. 0 kJ 31. 5 kJ 61. 5 kJ.
