Answer:

#"Molar mass of copper"/"Molar mass of copper sulfate"# #xx100%#

Explanation:

#(63.55*g*mol^-1)/((63.55+32.06+4xx15.999)*g*mol^-1)# #xx100%# #=# #?%#

Note that the anhydrous salt is white, but it dissolves in water to give a beautiful blue solution, due to the #[Cu(OH_2)_6]^(2+)# complex.
