Question
The mass of the 12C atom is 12 atomic mass units. What is its binding energy per nucleon of the 12C nucleus?mH = 1.007825 u, mn = 1.008665 u.
Explanation / Answer
the amu values of carbon 12 and 13 are taken from wiki carbon-12 --- ( carbon-13 in parenthesis ) reactants components mass ----------------------> products atom mass [ (Z)(mp + me) + (n)(mn) ] --------------------------> [ atom mass ] + [ binding energy ] mp=proton amu = 1.007 276 me=electron amu = 0.000 549 mn=neutron amu = 1.008 665 Z=protons = 6 --- ( 6 ) n=neutrons = 6 --- ( 7 ) calculated reactants amu = 12.10 --- ( 13.107 605 ) atom amu = 12.00 --- ( 13.003 350 ) mass defect amu = 0.10 --- ( 0.104 255 ) conversion factor= MeV/amu = 931.49 calculated binding energy = 92.16MeV --- ( 97.11 MeV )
