Question

How many hydrogen bonded water molecule(s) are associated in cuso4.5h2o

Answer 1

hydrogen bonded water molecule(s) are associated in cuso4.5h2o is 10 .

Answer 2

In CuSO4.5H2O, Cu is cordinated with 4 water molecules and two more oxygen atoms fron Sulphate ion.

Now fifth water molecule is hydrogen bonded and is deeply embedded in crystal. It is not cordinated.

Only 4 water molecules are coordinated and fifth is only hydrogen bonded.
