Homework Help: Nuclear Physics Find molar binding energy

  1. Nov 1, 2011 #1
    1. The problem statement, all variables and given/known data
    What is the molar binding energy of the carbon 12 nuclei?


    2. Relevant equations
    e=mc2


    3. The attempt at a solution
    proton mass = 1.00728u
    neutron mass: 1.00866u

    before: 6p+6n = 12.09564u
    after: carbon 12 = 12u
    delta m = 0.009564u

    E=mc2
    =(.009564u)(9x10^16kJ/g)

    now I don't know what to do, you can convert u and g to the same unit but they cancel out, so how do I get kJ/mol

    Your equation above is the energy per atom. How many atoms per mole?

    I'm getting 8.6 not 8.9 now... Carbon 12 is 12...
