Here's how to determine the number of atoms in a sulfuric acid molecule:

* Sulfuric acid's chemical formula is H₂SO₄.

* This formula tells us:

* There are 2 hydrogen atoms (H)

* There is 1 sulfur atom (S)

* There are 4 oxygen atoms (O)

Therefore, there are a total of 7 atoms in one molecule of sulfuric acid.
