Question

calculate the energy equivalent of 1a.m.u. (ans. in Mev)

Answer 1

We know that one atomic mass unit is defined as 1/12th the mass of an atom of Carbon-12 isotope.
As such 1 amu=1.6606×10−27 kg
Velocity of light c in vacuum is =2.9979×108 ms−1

Using the Einstein's mass energy equivalence relation we get
E=mc2
E=1.6606×10−27×(2.9979×108)2 J

We also know that 1 eV=1 electronic charge in C×1 V
=1.60218×10−19 J

Therefore, we get
E=1.6606×10−27×(2.9979×108)21.60218×10−19 eV
⇒E=931.5 MeV, rounded to one decimal
