For Apex the answer is 2
Well the atoms are Chlorine (Cl) and Hydrogen (H) and the molecule is HCl which is made of one Chlorine atom and one Hydrogen atom (2 atoms altogether) However the "2" in the front of "HCl" means that there are two molecules of HCl and therefore there are FOUR atoms present.
There is 1 zinc (Zn) atom in Zn(ClO3)2.
There are 6 oxygen atoms in Zn(ClO3)2.
There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.
To find the number of moles, divide the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol). For 1.33 x 10^24 Zn atoms, we have: 1.33 x 10^24 Zn atoms / 6.022 x 10^23 atoms/mol ≈ 2.21 moles of Zn atoms.
There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.

1 atom of Zn (zinc) + 2 atoms of N (nitrogen) + 6 atoms of O (oxygen) = 9 atoms in 1 molecule of Zn(NO3)2.

There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.
Zn(ClO3)2 has two chlorine atoms
