Among the presented substances, Phosphoric acid - H₃PO₄ is the one made up of most atoms.

What is atomicity?

Atomicity refers to the number of atoms of each element in a compound. It is given by the corresponding subscripts.

We have 4 substances. To calculate the number of atoms in each one, we will sum the number of atoms that form them.

  • Carbonic acid - H₂CO₃

H + C + O = 2 + 1 + 3 = 6 atoms

  • Nitric acid - HNO₃

H + N + O = 1 + 1 + 3 = 5 atoms

  • Phosphoric acid - H₃PO₄

H + P + O = 3 + 1 + 4 = 8 atoms

  • Sulfuric acid - H₂SO₄

H + S + O = 2 + 1 + 4 = 7 atoms

Among the presented substances, Phosphoric acid - H₃PO₄ is the one made up of most atoms.
