Calculating Average Atomic Mass 2C. How To Calculate Relative Atomic Mass Table of Contents. Atomic Mass Chemwiki Physical Chemistry Relative Atomic Mass Mass Spectrometry UnderstandingsThe mass spectrometer is used to determine the relative atomic mass of an element from its isotopic compositionApplications and skills. . 26Mg 223 00870. The relative atomic mass of such element is determined by the masses of all the isotopes and is closer to the mass of the more abundant isotope. Some elements have been found to contain isotopes. The first isotope has an atomic mass of 3496885 and has an abundance of 7578. These percentages are applied to the isotopic masses to find the relative atomic mass of the sample. A_r frac35 times 75 37 times 25100. The relative atomic mass of these elements can be calculated using the formula. It could also be calculated this way. The formula for relative atomic mass is A r averag...
