Quinine is an important type of molecule that is involved in photosynthesis. the transport of electrons mediated by quinone in certain enzymes allows plants to take water, carbon dioxide, and the energy of sunlight to create glucose. a 0.1964-g sample of quinone (c6h4o2) is burned in a bomb calorimeter with a heat capacity of 1.56kj/c. the temperature of the calorimeter increases by 3.2 degrees c. calculate the energy of combustion of quinone per gram and per mole.
