How much mass would a mole of oxygen molecules contain? Recall that oxygen is diatomic. approx g/mol

To determine the mass of a mole of oxygen molecules, we need to consider that oxygen is diatomic, meaning each molecule consists of two oxygen atoms.<br /><br />1. **Atomic Mass of Oxygen:**<br /> The atomic mass of a single oxygen atom (O) is approximately 16 grams per mole (g/mol).<br /><br />2. **Molecular Mass of Oxygen (O₂):**<br /> Since an oxygen molecule (O₂) consists of two oxygen atoms, its molecular mass is:<br /> \[<br /> \text{Molecular mass of O}_2 = 2 \times 16 \, \text{g/mol} = 32 \, \text{g/mol}<br /> \]<br /><br />Therefore, the mass of one mole of oxygen molecules (O₂) is approximately 32 grams per mole (g/mol).
