Since 1 u is equivalent to 931.494013 MeV, ∆Ebe= (2.051245 u)(931.494013 MeV/u) = 1910.722 MeV. Since there are 259 nucleons, the binding energy per nucleon is ∆Eben= E/A= (1910.722 MeV)/259 = 7.38 MeV. 20. The binding energy is given by ( )2beRfHnEZmAZmMc∆=+−−⎡⎤⎣⎦, where Zis the atomic number (number of protons), Ais the mass number (number of nucleons), mHis the mass of a hydrogen atom, mnis the mass of a neutron, and
