Combustion (bomb) calorimeter. The heat capacity of the calorimeter was determined in a previous experiment to be $855.9\mathrm{J}\cdot {}^{\circ }{\mathrm{C}}^{-1}$. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data. ${\mathrm{C}}_{14}{\mathrm{H}}_8{\mathrm{O}}_4(s)+14{\mathrm{O}}_2(g)\to 4{\mathrm{H}}_2\mathrm{O}(l)+14{\mathrm{CO}}_2(g)+\text{ Energy }$ Molar Heat of Combustion = $\mathrm{kJ}/\mathrm{mol}$
