Question

how many total atoms are in al₂(so₄)₃? 17 3 12 24

Explanation:

Step1: Analyze each element's atom count

• For \(Al\): The subscript is \(2\), so there are \(2\) \(Al\) atoms.
• For \(S\): Inside the parentheses, there is \(1\) \(S\) atom, and the outer subscript is \(3\). So the number of \(S\) atoms is \(1\times3 = 3\).
• For \(O\): Inside the parentheses, there are \(4\) \(O\) atoms, and the outer subscript is \(3\). So the number of \(O\) atoms is \(4\times3=12\).

Step2: Calculate the total number of atoms

Add up the number of atoms of each element: \(2 + 3+12\).

$$2+3 + 12=17$$

Answer:

\(17\)
