Here's how to determine the number of hydrogen atoms in ammonium sulfate:

1. Chemical Formula:

Ammonium sulfate has the chemical formula (NH₄)₂SO₄.

2. Breakdown:

* (NH₄)₂: This indicates two ammonium ions (NH₄⁺).

* SO₄: This is the sulfate ion (SO₄²⁻).

3. Counting Hydrogen:

* Each ammonium ion (NH₄⁺) has 4 hydrogen atoms.

* Since there are two ammonium ions, there are a total of 2 * 4 = 8 hydrogen atoms.

Answer: Ammonium sulfate ((NH₄)₂SO₄) has 8 hydrogen atoms.
