Given, mass of ‌1429Si=28.976495u
Now, mass of 14 protons
=14× mass of 1 proton
=14×1.007276=14.101864u
Also, mass of 29−14=15 neutrons =15× mass of 1 neutron
=15×1.008664=15.12996
Total mass of constituents of Si atom
So, mass defect = mass of constituents − mass of atom
Binding energy = Energy equivalent of mass defect
=∆M×931.5MeV
=0.255329×931.5=237.84MeV
