The number of hydrogen bonded water molecule(s) associated with stoichiometry

CuSO_{4} \cdot 5 H_{2} O

Answer: 1

Solution

CuS O_{4} \cdot 5 H_{2} O

, four of the five water molecules are coordinated directly to the

C u^{2 +}

ion, while the fifth is held in the lattice only by hydrogen bonds, bridging the coordinated water and the sulphate ion. The number of hydrogen-bonded water molecules is 1.
