This equation will return the Atomic Weight of the selected element.  The element symbols are listed in alphabetic order.

Units for Atomic weight are expressed in grams per mole. This equation represents the atomic weight of elements from the periodic table.  Isotopes and molecular compositions are not represented in this equation.


Molar mass is a physical property of an atomic element. It is defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance.[1] The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
