The mass of deutron (1H2) nucleus is 2.013553 a.m.u. If the masses of proton and neutron are 1.007275 a.m.u. and 1.008665 a.m.u. respectively, calculate the mass defect, the packing fraction , binding energy and binding energu per nucleon.
Mass defect = Mass of atom − Mass of neutron and proton
Mass defect =2.013553−(1.007275+1.008665)=0.002387
Binding Energy =0.002387×931=2.22MeV
Binding Energy per nucleon =2.222=1.11MeV
