You are being asked to apply the definition of atomic mass to calculate an atomic mass.  What key words does the question contain and what do they mean? o Atomic mass is the sum of the masses of protons and neutrons in an atom. We assume the mass of electrons is so small it doesn’t contribute to total mass. Gather Content  What do you know about atomic mass? How does it relate to the question? o The masses of a proton and of a neutron are both 1. Consider Possibilities
