How do isotopes relate to average atomic mass?. That also determines the atomic mass, which is the average "weight" of that. New 2017 Answer Gear In Stock. Neon consists of 3 isotopes with masses 19.92, 20.99, and 21.99 amu. The average atomic mass is calculated taking into account the different percents of each isotope present. If we add these two masses we arrive at 56.68. Answers.com WikiAnswers Categories Science Chemistry Elements and Compounds Atoms and Atomic Structure Atomic Mass What is the average atomic mass Is An atom's atomic mass unit is equal to the weighted average of the masses of all the naturally occurring isotopes of that element?. (75.23 amu) (0.241) + (74.61 amu) (0.487) + (75.20 amu) (0.272) = the answer more like this: .

You then multiply each isotopes weight by its certain percentage and add all answers together. Every isotope (at least, the ones that occur naturally) contributes to the average atomic mass, which appears in the element's box on most periodic tables. How can you find average atomic mass. Isotopes are forms of the same atom that vary in mass.
