WebThe average atomic mass of an element is a weighted average calculated by multiplying the relative abundances of the element's isotopes by their atomic masses and then summing the products. The relative abundance of each isotope can be determined using mass spectrometry.

WebFind the atomic mass for each element using the mass shown in the Periodic Table or Atomic Weight Table. Multiply the subscript (number of atoms) times that element’s atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass. Molar mass is typically expressed in either gram ( g) or kilograms (kg).
