Answer:
We do not simply state that the mass of a C atom is 12 AMU because elements exist as a variety of isotopes. ... Each carbon atom has the same number of protons and electrons, 6. 12C has 6 neutrons, 13C has 7 neutrons, and 14C has 8 neutrons and so on. So, we must specify which C atom defines the scale.
