Answer :
We know that an alpha particle consists of two protons and two neutrons.
Mass of proton = 1.007276 u
Mass of neutron = 1.008665 u
Where u = 1.6605402 × 10-27 kg (Atomic mass unit)
Let the mass of the alpha particle be M
∴ Mass defect is ΔM,
Given, Binding energy = 28.2 MeV
Binding energy is also equal to
So,
[Note ]
Hence, the mass of an alpha particle is 4.0016u
