Calculate the equivalent energy in MeV of a unified atomic mass unit.

Explanation

Einstein.s mass energy relation is `E=(Deltam)c^2`
where E is the energy released due to loss in mass `Deltam and c` is the speed of light
Given `Deltam=1" "a.m.u=1.655xx10^(-27)kg" then"`
`E=(1.655xx10^(-27))xx(3xx10^8)^2J=1.4895xx10^(-10)J`
`=(1.4895xx10^(-10))/(1.6xx10^(-19))eV=931xx10^6eV=931MeV`
