How many hydrogen bonded water molecules does CuSO4.5H2O have?

In Cupper Sulphate pentahydrate (CuSO₄.5H₂O) Cu is coordinated with 4 water molecules and two more oxygen atoms from Sulphate ion. And hence the coordination number of Cu (II) ion is six and hybridization is sp3d2 with distorted octahedral geometry. Now fifth water molecule is hydrogen bonded and is deeply embedded in crystal.

Thus it is clear that four (4) water molecules are coordinated and one (fifth one) water molecule is bonded with hydrogen bond. And its formula also written as [Cu(H₂O )₄SO₄].H₂O

What is the difference of dipole moment of NH3 and NF3 respectively?

 Both NH3 and NF3 have sp3 hybridization and trigonal pyramidal shape.

Fluorine has more electronegative than nitrogen but NH₃ has more dipole moment than NF₃.  In NH3, Nitrogen is more electronegative than Hydrogen. So Nitrogen pulls the electrons from Hydrogen towards itself and so, the direction of moment due to the N-H bonds is in the same direction as that of the lone pair of electrons on Nitrogen. Hence here additive effect appears while in case of NF₃, Fluorine is more electronegative than Nitrogen. So fluorine pulls electrons from nitrogen towards itself  so that direction of moment due to N-F bonds is in the opposite direction as the lone pair of electron on nitrogen atom. Hence it is clear dipole moment of NH₃ is more than NF₃.
