Final answer:
The heat of combustion per gram of quinone can be determined using a bomb calorimeter to measure the change in temperature upon burning a known mass of quinone; this heat is then divided by the substance's mass to obtain the enthalpy of combustion per gram.
Step-by-step explanation:
The heat of combustion per gram of a substance is the amount of heat energy released when one gram of the substance is completely burned in oxygen. Depending on the molecular structure of a compound, such as quinone, its heat of combustion can be determined experimentally using a bomb calorimeter. The process involves burning a known mass of the compound and measuring the temperature change of the calorimeter. Typically, the heat of combustion is reported in units of kJ/g or kJ/mol, making it an important property for characterizing the energy content of fuels and other combustible materials.
To calculate the heat of combustion per gram, the calorimeter's heat capacity must be known, and the mass of the compound being combusted must be precisely measured. The change in temperature is then used to calculate the heat generated during combustion. This value is divided by the mass of the substance to get the enthalpy of combustion per gram. While I do not have the specific heat of combustion value for quinone, this process can be applied to determine it accurately.
