Number of atoms in a 3g coin=

\frac{6.023 \times 1 0 ^{23} \times 3}{63} = 2.868 \times 1 0^{22}

Each copper atom has 29 protons and and 34 neutrons.

Thus, the mass defect of each atom is

29 \times 1.00783 + 34 \times 1.00867 - 62.92960 = 0.59225 u

Total mass defect of all atoms =

0.59225 u \times 2.868 \times 1 0^{22} = 1.6985 \times 1 0^{22} u

Thus, the nuclear energy required=

1.6985 \times 1 0^{22} \times 931 M e V = 1.58 \times 1 0^{25} M e V
