The gram formula unit mass of copper (II) sulfate pentahydrate is 249.68. The gram formula unit mass of water is 18.015. Therefore, the mass of water of crystallization present in 50.0 g of copper (II) sulfate pentahydrate is:
50[5(18.015)/249.68] or 18.0 g, to the justified number of significant digits. (Note that the prefix penta- means five)

What is the oxidation number of copperII?
+2 for Copper(II)
How do I calculate the molar solubility of copperII sulfide in 25M of CuCl2?
You need the Ksp of copper sulphide. From that you can use the equation for solubility product - Ksp = [Cu2+].[S-] where the Cu2+ term becomes 25M.
If you wish to obtain 10.0 grams of copper metal from copperII sulfide what mass of copperII sulfide must you use - A.10.0 grams B.24.6 grams C.607 grams or D.15.0 grams?

What is the molar mass of copperII hydroxide?
There are 2 forms of Copper(II) Sulphate, each with a different molar mass. * Copper(II) Sulphate Pentahydrate (CuSO4.5H20) This is the more common, blue, crystalline solid. it has a molar mass of: 249.7g mol-1 * Anhydrous Copper(II) Sulphate (CuSO4) This is less common to come across, it is a white powdery solid,and can be obtained by heating the pentahydrated form. Molar mass: 159.6g mol-1
