(b) Calculate the dinding energy per nucleon of plutonium-239, miven Mn 1.0086649 u, m (hydrogen-1 atom)=1.0078250 u, and m (plutonium-239 atom) =239.052157 u.

Solutions

Expert Solution

The rest mass of the baryon in units of atomic mass units is calculated as follows:

  

Therefore, the rest mass of the Baryon in amu is 1.197746 u.
