The question asks about the number of atoms in 3 molecules of . Let's break down the formula and count the atoms:* **Al (Aluminum):** There are 2 aluminum atoms per molecule.* **S (Sulfur):** There are 3 sulfur atoms per molecule.* **O (Oxygen):** There are 12 oxygen atoms per molecule (3 x 4).**Total atoms per molecule:** 2 + 3 + 12 = 17 atoms**Total atoms in 3 molecules:** 17 atoms/molecule * 3 molecules = 51 atoms**Therefore, the correct answer is E. 51 atoms.**
