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 WebAtomic mass is most conveniently described by the atomic mass unit, which is 1/12 of the mass of a carbon-12 atom. This means that each proton and each neutron contribute 1 amu to the mass of an atom, which makes it very easy to calculate. You can also use this to account for different isotopes.
