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.

Explain why the name for MgCl2 is magnesium chloride but the name for CuCl2 is copperII chloride?

They are identical - bonding two elements to form a binary compound. The only difference is that copper can be found as copperII or copperIV so it's correct to specify which one, that's all. Save with Pb (lead) and other unique metals/nonmetals.

The compound CuCl2 is named copperII chloride explain why a roman numeral is used in one name but not the other?

In the chemical formula CuCl2 it is obvious for a neutral ionic substance that copper has a +2 charge, since Cl only comes in -1 charge, but in the stock name of copper chloride, it is unclear whether it is CuCl2 you are talking about or CuCl, which has a +1 Copper, thus in the name, the charge of the metal is differentiated by the roman numeral in parenthesis after the metal. This stock system (using numerals) is much easier to read than the previous traditional system of naming the higher charge metal with the -ic ending and the lower charged metal with the -ous ending, where CuCl2 and CuCl would be cupric chloride and cuprous chloride, respectively.
