Calculate oxygen molecular weight using atomic mass values with simple accurate conversion steps and detailed chemistry information.
The formula for calculating oxygen molar mass is:
Molar Mass = Atomic Mass × Number of Atoms
For oxygen gas, O₂ contains two oxygen atoms. The calculation is 15.999 × 2 = 31.998 g/mol.

The answer shows the total molecular mass. Values are displayed in grams per mole. This helps chemistry calculations become faster.
| Compound | Atoms | Molar Mass |
|---|---|---|
| Oxygen O₂ | 2 | 31.998 g/mol |
| Single Oxygen Atom | 1 | 15.999 g/mol |
Oxygen is an important chemical element. It is represented by the symbol O. Its atomic number is eight.
Molar mass shows the mass of one mole. A mole contains a fixed number of particles. Chemists use this value in reactions.
Oxygen commonly exists as a diatomic molecule. This means two atoms form one molecule. The molecular formula becomes O₂.
The atomic mass of oxygen is 15.999. Two atoms create the molecular weight. Therefore oxygen gas has 31.998 g/mol.
This calculator simplifies chemistry calculations. Students and professionals can verify values. It reduces manual calculation errors.
