The atomic mass of Potassium 39 is 38.96371 AMU. Calculate the binding energy for a mass of this nuclide using 1.008665 AMU for the mass of the neutron, 1.007276 AMU for the mass of the proton, 0.00054858 AMU for the mass of the electron, and 2.9979 x 10^8 m/s for the speed of light. 1 AMU = 1.6605655 x 10^-27 kilograms. That is, calculate the total binding energy of 1 mol of K-39 atoms. It should be a rather large (but negative) number.
