gpt
32.0 grams of oxygen gas.
Explanation: Oxygen gas is a diatomic molecule composed of two oxygen atoms per molecule. Based on the atomic mass of oxygen (approximately 16 grams/mole), one mole of oxygen gas (O2) would consist of two moles of oxygen atoms, each comprising 32 grams for a final total of 32 grams for one mole of O2.
