The atomic mass of an atom is determined by adding the number of protons, neutrons, and electrons in a single atom. The average atomic mass is a weighted calculation and is very similar to the Atomic Mass. This difference does not usually affect overall calculations. This difference is due to the different isotopes.
Average of atomic mass determined by 1/12 time of carbon element
Italian chemist Stanislao Cannizzaro is credited for the determination of standard relative atomic masses.

The atomic mass that you see on the periodic table is an average mass taken from all of the element's known isotopes. Simply find the average of all of the masses of the isotopes of an element.
"Atomic Mass" is not an average, it is tje total mass of all the electrons, protons and neutrons in an atom of an element. AVERAGE Atomic Mass is the AVERAGE of the Atomic Masses of all of the Isotopes of an element according to their natural proportions.
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
Average weight of an element expressed in Atomic Mass units.
atomic mass is determined by adding the number of protons and neutrons.this can be seen in the periodic table as the average atomic mass below the name of the element
The atomic mass that you see on the periodic table is an average mass taken from all of the element's known isotopes. Simply find the average of all of the masses of the isotopes of an element.
the Atomic Mass in g/ml is the molar mass of the element
the Atomic Mass
the Atomic Mass in g/ml is the molar mass of the element
It is the same as the element’s atomic mass, but in grams.

The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
