Calculation for 1a.m.u (atomic mass unit)

 Calculations for 1 a.m.u.:

 

        Calculated mass of Helium Nucleus

        Mass of Proton             2 x 1.0078=       2.0156

        Mass of Neutron          2 x 1.0087=        2.0174

                                                                        4.0330

        Actual mass of Helium Nucleus      (-)   4.0026

        Difference of the Mass                           0.0304

        Binding Energy of the Helium atom= 0.0304 x 931.5 = 28.3176MeV
