Using the Einstein relationship:
Nuclear binding energy = Δmc^2
number of protons x 1.007825 x 931.5 Me V = X
number of neutrons x 1.008665 x 931.5 Me V = Y
Adding up these energies = X + Y
59.933820 x 931.5 Me V = Z
Subtract Z from (X+Y)
(X+Y) -Z = Nuclear binding energy
Divide by the total number of nucleons by the sum of all protons and neutrons in Co 60
(524.807 Me V)/(60 nucleons) = 8.74678 Me V/nucleon.
