Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1 meaning you need 3 chlorine for every 1 Aluminum to cancel the charges.
Because of the chlorine, it would most likely be aqueous, or dissolved in a liquid.

The formula unit of aluminum nitrate is Al(NO3)3. This shows that the formula unit contains 1 aluminum atom, 3 nitrogen atoms, and 9 oxygen atoms for a total of 13 atoms.
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.

In a diamond unit cell, each carbon atom is located at the corners of the unit cell. Since there are eight corners in a unit cell, each shared by 8 adjacent unit cells, the contribution to the total number of carbon atoms is 1/8 of a carbon atom per unit cell. Therefore, there is 1 carbon atom per unit cell.
Count them :- Al = 1 Cl = 3 that makes 4 atoms
The formula unit for aluminum nitrate has the formula Al(NO3)3. Subscripts within parentheses are multiplied by the subscript after the parentheses. Therefore, this formula unit contains nine oxygen atoms, three nitrogen atoms, and one aluminum atom for a total of 13 atoms.
