The molecular formula of sulfuric acid is H₂SO₄. To determine the number of atoms in a molecule of H₂SO₄, we can count the individual atoms present in the formula.
H₂SO₄ consists of two hydrogen (H) atoms, one sulfur (S) atom, and four oxygen (O) atoms.
Therefore, the total number of atoms in a molecule of H₂SO₄ is 2 (hydrogen) + 1 (sulfur) + 4 (oxygen) = 7 atoms.
