Determine Atomic Mass
1. Find the number of protons in the nucleus by multiplying the atomic number by the charge on the proton.
2. Find the number of neutrons in the nucleus by subtracting the number of protons from the atomic number.
3. Multiply the number of protons by the mass number to find the total mass of the atom.
4. Divide the mass number by the atomic number to find the average mass per nucleon.
