Consider a star of mass M=10Msun, composed entirely of fully ionized C-12. Its core temperature is 6*10^8K. Suppose the star produces energy via the reaction C12 + C12 --> Mg24. the atomic weight of C12 is 12, and that of Mg24 is 23.985. What fraction of the star's mass can be converted into thermal energy?
