Answer:
The mass defect of cobalt-60 is 0.56307 u.
Explanation:
The isotope Cobalt-60 has a nuclear mass of 59.933820 u
Mass of a Proton: 1.007825 u
Mass of a Neutron: 1.008665 u
1 u = 931.5 MeV
We take the PARTICLE masses of 27 protons
, and 33 neutrons.
(Excluding mass of Electrons)
∴ 27 × 1.007825 u. + 33 × 1.008655 u. - 59.933820 u. = 0.56307 u.
