The size of an O2 molecule, which consists of two oxygen atoms, is approximately 0.12 nanometers (or 1.2 angstroms) in diameter. However, in practical terms, the size of O2 is often considered in the context of its behavior in gases, where it occupies space and interacts with other molecules. In terms of molecular weight, O2 has a molar mass of about 32 grams per mole.
