Identify the chemical formula of the molecule given: H_2SO_4.
Break down the formula into individual atoms and their quantities: H (hydrogen) = 2 atoms, S (sulfur) = 1 atom, O (oxygen) = 4 atoms.
Add the number of atoms together to find the total number of atoms in one molecule: total atoms = 2 (H) + 1 (S) + 4 (O).
Perform the addition to get the total number of atoms in the molecule.
Conclude that the total number of atoms in one molecule of H_2SO_4 is the sum calculated.
