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

1. Identify the chemical formula:

Ammonium sulfate has the formula (NH₄)₂SO₄.

2. Breakdown the formula:

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

* SO₄: This represents one sulfate ion (SO₄²⁻).

3. Count the hydrogen atoms:

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

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

Therefore, there are 8 hydrogen atoms in the formula for ammonium sulfate.
