Answer: Atomic Mass
Explanation:
The Atomic mass of an atom is the number of protons and neutrons in the atom and is measured in atomic mass units (amu) but can still be measured in kilograms.
For example, if the number of neutrons in an atom is 8 and the number of protons is 6, the atomic mass of the atom is 14.
N(Ca)/2 = n(O)/1 = n(CaO)/2
The calcium and the Calcium Oxide are divided by 2 because of their coefficients
there is no number in front of the oxygen so it is over one.
