What is the Molar Mass of Oxygen Gas? | Free Expert Q&A
The molar mass of a chemical substance is the mass of one mole, or 6.023 × 10²³ particles, of that substance in grams. For every element, the molar mass in grams per mol (g/mol) is equal to its atomic mass in atomic mass units (amu). The atomic mass is available on the periodic table, below the element’s symbol and name.
