i. The nuclear mass is expressed in atomic mass unit (u) which is exactly 1/12th of the mass of 12C atom. Thus, u = 1/12th mass of C12 atom = 1.66 × 10-2 kg.
ii. The conversion of mass into energy is established through Einstein’s equation, E = mc2 .
Where m is the mass of matter converted into energy (E) and velocity of light (c).
iii. The energy released in the conversion of one u mass into energy is given by:
E = mc2 = (1.66 × 10-27 kg) × (3 × 108 m s-1)2
