WebYou can use an average atomic mass calculator for calculating the atomic mass of oxygen (O). However, if you want to do this manually then add the atomic number of oxygen and the number of neutrons in a given isotope. Atomic number of oxygen = 8 The total number of neutrons in a given isotope = 9 The atomic mass of oxygen atom = 8 + 9 = 17 WebAverage Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ...... The average atomic mass has been calculated in this fashion and can be found under every symbol in the periodic table. Let us see one such example of how we can calculate this information.
