* Parentheses and Subscripts: The parentheses indicate that the entire group within them (SO) is multiplied by the subscript outside the parentheses.

* Multiplying Subscripts: The subscript "8324" next to the "O" means there are 8324 oxygen atoms within each (SO) group. The subscript "8323" outside the parentheses means there are 8323 of these (SO) groups.

Calculation:

1. Sulfur per group: There's one sulfur atom (S) in each (SO) group.

2. Total sulfur atoms: Since there are 8323 (SO) groups, there are a total of 8323 sulfur atoms.

Answer: There are 8323 sulfur (S) atoms in the chemical formula 3Al and 8322(SO 8324) 8323.
