    [Fusion cycle of the SUN]
    Show that in the fusion cycle, the energy released is about 30 MeV.

    2. Relevant equations

    3. The attempt at a solution
    Can you do this without any relevant information!?
    If you have the binding energy per nucleon graph, can you do it?

    Hmmm.... I'd consider the possibility that whoever assigned you that problem is expecting you to dig out the relevant data.... Indeed, that's probably the point of the problem, because once you have the relevant data there's not much to the problem at all....

    Try asking yourself about the masses of the various components in the various reactions.

    You might also want to look hard at all three reactions. One of them smells funny.
