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.

How is average atomic mass determined from isotopic 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.
What is atomic mass an average of?
"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.
How you determined the relative atomic mass of oxygen?
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?
Average weight of an element expressed in Atomic Mass units.
What is the difference between average atomic mass and atomic mass?
The atomic mass is determined by?
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
How is average atomic mass determined from isotopic 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.
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
How is the mass of 1 mole of an element determined?
It is the same as the element’s atomic mass, but in grams.
What is atomic mass an average of?
"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.

Average weight of an element expressed in atomic mass units?
Average weight of an element expressed in Atomic Mass units.
The average atomic mass of an element is the average of the atomic masses of its?
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.
What is the difference between average atomic mass and atomic mass?
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
