Final answer:
There are 8 hydrogen atoms in one molecule of (NH₄)₂SO₄.
Step-by-step explanation:
The formula for (NH₄)₂SO₄ is ammonium sulfate. To determine the number of hydrogen atoms present in one molecule of (NH₄)₂SO₄, we need to count the number of hydrogen atoms in the formula. There are 8 hydrogen atoms in one molecule of (NH₄)₂SO₄.
