-A proton has a mass of 1.00728 amu. A neutron has a mass of 1.00866 amu. One carbon-12nucleus contains six protons and six neutrons. Calculate the total mass of the protons and neutrons in carbon-12. *
-A scientist measures a carbon-12 atom and finds it has a mass of exactly 12 amu. How does this compare to the sum of the protons and neutrons in carbon-12? How can you explain this difference in mass?
