The chemical formula is CuSO4.5 H2O; the pentahydrate contain 5 molecules of water (penta = five, in the Greek lanuage).
The most common form is the pentahydrate.
Each molecule of copper (II) sulfate pentahydrate (the blue form) contains 5 molecules of water.
The solubility of copper sulfate pentahydrate at 100 0C is 114 g/100 g water.

If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
The most common form is the pentahydrate.
Each molecule of copper (II) sulfate pentahydrate (the blue form) contains 5 molecules of water.
Six water molecules are bound to iron (II) ammonium sulfate.
The solubility of copper sulfate pentahydrate at 100 0C is 114 g/100 g water.
1,125 moles of sodium sulfate contain 6,774908464125.10e23 molecules.

As magnesium sulfate is an ionic compound, it creates an ionic lattice. Therefore it doesn't exist as seperate molecules.
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
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.
The chemical name is usually "water" for H2O regardless of how many there are. In naming a hydrate such as CuSO4.5H2O we first name the compound before the "dot". Here it is "copper(II) sulfate". Then use the prefix for the number of water molecules attached. Here it is "penta" for five. The "dot" tells us that it is a hydrate. The name of CuSO4.5H2O would be "copper(II) sulfate pentahydrate".
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
The calcium ion has 18 electrons. The sulfate ion has 16 electrons from sulfur, 32 electrons from oxygen atoms and two from the charge. Altogether, a (molecule) of calcium sulfate has 68 electrons. * Calcium sulfate is not existing as molecules, 'formula unit' is a better phrase.
