Homework Help: Nuclear fusion

  1. Aug 24, 2010 #1
    1. The problem statement, all variables and given/known data

    How much energy, in joules, is released when one mole of helium-4 nuclei is formed from its individual protons and neutrons?

    2. Relevant equations

    2p + 2n ----> He-4 (p is proton n is neutron)

    3. The attempt at a solution

    Book sucks at explaining so Im not quite sure where to start. Calculate energy for each nucleon maybe?

    You will need exact masses of protons, neutrons and product.
