Weba. Using the average atomic mass of the element, calculate the number of atoms present in 80.16 amu of caicium. atom (s) b. Using the average atomic mass of the element, calculate the number of atoms present in 735.6 amu of tungsten. atom (5) c. Using the average atomic mass of the element, calculate the number of atoms present in 384.58 amu of ... WebThe binding energy that holds the protons and neutrons together comes from some amount of mass such that E=mc^2. If you change the number of bound neutrons or protons, you also change the energy required to bind them together, thus the total mass changes. This is also why individual, unbound protons or neutrons have a mass more than 1 u.
