Answer:
One sulfur atom
Explanation:
The compound ZnSO₄ is made up of:
1 atom of Zn
1 atom of S
4 atoms of O
These atoms combines chemically to form the above compound. The coefficient 3 before the compound only shows the number of moles of the compound that are there. Most times, the coefficient balances the chemical equation.
Therefore, we can say 3 moles of ZnSO₄ consists of 1 atom of Zn, 1 atom of S and 4 atoms of Oxygen.
