Atomic Mass - Atomic weight are the same , so look at your Periodic Table and below every element it will give you atomic mass.
Unified atomic mass unit
your mom is the atomic weight of a carbonate
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
Selenium (Se) has an atomic weight of 79,04.
The atomic weight of argon is approximately 39.95 atomic mass units.
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.

Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
Whenever you are talking about a precise figure. e.g. the weight atomic weight of a hydrogen atom is exactly 0.0253 mol.
Atomic weight = Weight of protons + Weight of neutrons
Unified atomic mass unit
Atomic Number = 6. Atomic Weight = 12.011
