There are :
1 zinc atom
2 chlorine atoms
6 oxygen atoms
in this zinc chlorate molecule.
First you need to figure out how much zinc is in the compound. The easiest way is to find the percent of Zn in ZnCl and apply it to the mass given. To do this you need the atomic masses and the molecular mass of ZnCl (added atomic masses).
Zn- 65.4
Cl- 35.5
ZnCl- 100.9 grams
65.4 / 100.9 × 100 = 64.8% of ZnCl is Zn
Because we know that in every sample of ZnCl will be composed of 64.8% Zn, we can take 64.8% of 4 moles to find the mass of Zn.
64.8% of 4.00 moles = 2.592 moles Zn in 4 moles ZnCl
The formula unit for a metal, such as zinc, is a single atom. Therefore, the number of atoms in 4.4 moles is 4.4 X Avogadro's Number or 2.65 X 1024 atoms.
There is 1 atom of Zinc.
There are 2 atoms of Chloride.
There are 3 total in one formula unit: 1 of zinc and 2 of chlorine.
The formula weight for Zn is the same as the atomic weight. Therefore, the answer is 4.30 X Avogadro's number.
1 mole of zinc has 6.023 x 1023 atoms
So, 4.1 moles will have 4.1 x 6.023 x 1023 atoms = 24.694 x 1023 atoms
One.

Zn(ClO3)2 has two chlorine atoms
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 are 3 elements in ZnSO4: zinc (Zn), sulfur (S), and oxygen (O).

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

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