WebAtomic Mass. It can be best defined as 1/12 of the mass of a carbon-12 atom in its ground state. The mass of an atom can be accounted for by the sum of the mass of protons and neutrons which is almost equal to the atomic mass. This small change is due to the binding energy mass loss. Web30 de mar. de 2024 · Then obviously by subtracting the atomic mass of oxygen: $$M_\mathrm {r} = 5A\mathrm {r} (\ce {O}) + 2A_\mathrm {r} (\ce {X}) \quad\Rightarrow\quad A_\mathrm {r} (\ce {X}) = 16\tag {6}$$ But that is not possible, as $16$ is the atomic mass of oxygen and there is no such thing as $\ce {O2O5}$ as far as I know.
