Oxygen-16 is by far the most abundant, comprising over 99. The presence of the heavier isotopes oxygen-17 and oxygen-18, while minor, pulls the average atomic mass slightly above the integer 16.
Why Oxygen's Rounded Atomic Mass Is 16 Despite Slight Variations
Practical Measurement and Standards The value of the gram atomic mass is maintained by international scientific standards, ensuring consistency across global research and industry. This is why the precise value is 15.
Application in Stoichiometry Stoichiometry relies heavily on the gram atomic mass to balance chemical equations and predict the outcomes of reactions. For instance, in a water molecule (H₂O), the molar mass is determined by adding the mass of two hydrogen atoms to the mass of one oxygen atom.

In contrast, oxygen gas is diatomic, meaning it exists as pairs of atoms. This constant allows for precise calculations in stoichiometry, enabling the prediction of product yields and the conservation of mass in chemical reactions.
