1. Understand the Concept:
* Molar mass: The mass of one mole of a substance.
* Oxygen gas (O₂): Oxygen exists as a diatomic molecule (two oxygen atoms bonded together).
2. Find the Molar Mass of Oxygen Gas:
* The molar mass of oxygen (O) is approximately 16 g/mol.
* The molar mass of oxygen gas (O₂) is 2 * 16 g/mol = 32 g/mol.
3. Calculate the Weight:
* Weight = Moles * Molar Mass
* Weight = 0.8834 mol * 32 g/mol
* Weight ≈ 28.27 g
Therefore, the weight of 0.8834 moles of oxygen gas is approximately 28.27 grams.
