Which of the following represents exactly atoms of oxygen? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

We need $1 \text{ mole}$ of oxygen atoms. <br>A) $16 \text{ g } O_2 = 1 \text{ mole atoms}$ (Wait, $16/32 = 0.5 \text{ mol } O_2$, which is 1 mol atoms. Correct). <br>B) $0.5 \text{ mol } O_2 = 1 \text{ mole atoms}$. <br>C) $1/3 \text{ mol } O_3 = 1 \text{ mole atoms}$. <br>D) $1 \text{ mol } H_2O = 1 \text{ mole atoms}$. <br>All options are correct.
