Atomic weight is the averagemassofatomsof anelement, calculated using the relative abundance ofisotopesin a naturally-occurring element. It is the weighted average of the masses of naturally-occurring isotopes. What Is It Based On? Prior to 1961, a unit of atomic weight was based on 1/16th ...
Average atomic mass is the weighted average of the atomic masses of the naturally occurring isotopes of an element Calculating a Weighted Average Example A box contains two size of marbles. If 25.0% have masses of 2.00 g and 75.0% have masses of 3.00 g what is the weighted average? (.250...

Atomic Mass vs. Mass Number: Unravel the Mystery By Todd Helmenstine Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes. The atomic weight can change because it depends on our understanding of how much of each isotope of an...
What is difference between mass number and atomic mass? Atomic mass is the weighted average mass of an atom of an element based on the relative naturalabundanceof that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus. ...
