<h3>Number of atoms in a compound</h3>
Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.
- The chemical formula for carbon dioxide is
. Thus, it has 2 atoms of oxygen. - The chemical formula for potassium chlorate is
. Thus, it has 3 oxygen atoms. - The chemical formula for calcium perchlorate is
. Thus, it has 8 atoms of oxygen. - The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
Therefore, the compound with the largest number of oxygen atoms is calcium perchlorate.
