Homework Help: Finding Binding Energy

  1. Mar 12, 2014 #1
    1. The problem statement, all variables and given/known data

    Calculate the binding energy per nucleon for each of the following nuclei. (Use the table of atomic masses as necessary.)

    (a) 2H


    (b) 24Mg


    (c) 32S


    (d) 238U


    These are all in MeV by the way.

    2. Relevant equations

    E=mc^2

    3. The attempt at a solution

    I found for example c:

    32-31.972071= .027929

    .027929*(3E8^2)/32

    What am I doing wrong?

    If you add units (always do this!), you should see an issue.
    Another problem: protons and neutrons don't weight 1u.
