The chemical formula 2Al(NO₃)₃ is incorrect. It should be Al₂(NO₃)₃.

Here's the breakdown:

* Al₂: This indicates two aluminum (Al) atoms.

* (NO₃)₃: This represents three nitrate (NO₃) groups.

* Each nitrate group contains:

* One nitrogen (N) atom

* Three oxygen (O) atoms

Therefore, the total number of atoms in Al₂(NO₃)₃ is:

* Aluminum (Al): 2 atoms

* Nitrogen (N): 3 atoms

* Oxygen (O): 3 x 3 = 9 atoms

Total: 2 + 3 + 9 = 14 atoms
