To determine the number of atoms in a molecule of H₂SO₄ (sulfuric acid), we can break down the molecular formula and count the individual atoms.
In H₂SO₄, we have:
- 2 atoms of hydrogen (H)
- 1 atom of sulfur (S)
- 4 atoms of oxygen (O)
Summing up the individual atoms, we have 2 hydrogen atoms (H₂), 1 sulfur atom (S), and 4 oxygen atoms (O₄) in a molecule of H₂SO₄.
Adding these together, the total number of atoms in a molecule of H₂SO₄ is 2 + 1 + 4 = 7.
Therefore, there are 7 atoms in a molecule of H₂SO₄.
