1. The Chemical Formula:
Aluminum sulfate has the chemical formula Al₂(SO₄)₃.
2. Breaking Down the Formula:
* Al₂: Indicates there are 2 aluminum (Al) atoms.
* (SO₄)₃: Indicates there are 3 sulfate (SO₄) groups.
3. Oxygen Atoms per Sulfate Group:
* Each sulfate group (SO₄) contains 4 oxygen (O) atoms.
4. Total Oxygen Atoms:
* Since there are 3 sulfate groups, the total number of oxygen atoms is 3 groups * 4 oxygen atoms/group = 12 oxygen atoms.
Therefore, there are 12 oxygen atoms in aluminum sulfate.
