* The Formula: The formula Al₂O₃ tells us there are 2 aluminum (Al) atoms and 3 oxygen (O) atoms in each molecule of aluminum oxide.
* The Coefficient: The coefficient "2" in front of Al₂O₃ means we have two molecules of aluminum oxide.
* Calculation:
* Oxygen atoms per molecule: 3
* Number of molecules: 2
* Total oxygen atoms: 3 atoms/molecule * 2 molecules = 6 oxygen atoms
Therefore, there are 6 oxygen atoms in 2Al₂O₃.
