SUMMARY
The heat of combustion for quinone (C6H4O2) can be calculated using the formula Q = C × ΔT, where Q is the heat absorbed, C is the heat capacity of the calorimeter, and ΔT is the change in temperature. In this case, with a heat capacity of 1.56 kJ/C and a temperature increase of 3.2 C, the total heat absorbed is 4.992 kJ. To find the heat of combustion per mole, divide this value by the number of moles of quinone in the 0.196 g sample, which is approximately 0.0011 moles, resulting in a heat of combustion of approximately 4,500 kJ/mol.
