What is Atomic Mass?

The mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom or to the average number allowing for the relative abundances of different isotopes.

What is Average Atomic Mass?

The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotope).
The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol. When data are available regarding the natural abundance of various isotopes of an element, it is simple to calculate the average atomic mass.
For helium, there is approximately one isotope of Helium-3 for every million isotopes of Helium-4; therefore, the average atomic mass is very close to 4 amu (4.002602 amu).Chlorine on the other hand, consists of two major isotopes, one with 18 neutrons (75.77 percent of natural chlorine atoms) and one with 20 neutrons (24.23 percent of natural chlorine atoms). The atomic number of chlorine is 17 (it has 17 protons in its nucleus).

How to Calculate Average Atomic Mass?

Average Atomic Mass calculator uses Average Atomic Mass = (Ratio Term of Isotope A*Atomic Mass of Isotope A+Ratio Term of Isotope B*Atomic Mass of Isotope B)/(Ratio Term of Isotope A+Ratio Term of Isotope B) to calculate the Average Atomic Mass, The Average Atomic Mass formula is defined as average of the atomic masses of element which exists in two different isotopic forms, namely 'a' and 'b' present in the ratio m:n. Average Atomic Mass is denoted by A.Mavg symbol.
