Question

Why 1 u = 931.5 Mev/c*2 ?

Answer 1

Answer:

For example, if the rest mass of a proton is converted entirely into energy, then E = mc2 = (938.27 MeV/c2)c2 = 938.27 MeV. It is useful to note that 1 u of mass converted to energy produces 931.5 MeV, or 1 u = 931.5 MeV/c2. All properties of a nucleus are determined by the number of protons and neutrons it has.
