Atomic Masses of  Cu=63.55 u
                               S =32 u
                               O =16 u
                               H =1 u
Molecular Mass of CuSO45H2O=[63.55+32+ 164+5(12+16)]u =249.55 u
Molecular Mass of Water=(12)+(161)=18 u
Mass of Water in 1 Molecule of CuSO45H20=(518)u=90 u
Percentage of water=90/249.55*100%=36.06%

Hope it helped :)
