Why is the atomic mass of copper not exactly 64?

(b) Explain why the atomic mass of copper is not exactly equal to 64 midway between the mass numbers of copper-63 and copper-65. There are only two isotopes of copper. Thus if we set the relative abundance of Cu-63 equal to the unknown variable x then the relative abundance of Cu-65 is equal to 1 – x.
