The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
WebTo calculate the average atomic weight, each isotopic atomic weight is multiplied by its percent abundance (expressed as a decimal). Then, add the results together and round off to an appropriate number of significant figures. (12.000000) (0.9893) + (13.003355) (0.0107) = 12.0107 amu. This is commonly rounded to 12.011 or sometimes 12.01.
