The unified atomic mass unit, denoted u, is defined to be 1u = 1.6605 × 10^-27 kg. It can be used as an approximation for the average mass of a nucleon in a nucleus, taking the binding energy into account. How much energy would you obtain if you completely converted a nucleus of 14 nucleons into free energy?
