Stellar nuclear fusion begins with H-1 and ends with Fe-56. younger stars fuse hydrogen to form He-4, while older, more massive stars fuse helium to form heavier elements. Fusion beyond Fe-56 is not possible because iron-56 has the greatest binding energy per nucleon. Calculate the binding energy per nucleon of Fe-56 and use it to calculate the maximum total energy per mole of Fe-56 that could be released through nuclear fusion. What percentage of the maximum total energy is released by the formation He-4?
