Answer:
The value of n in the hydrate formula is 5 ,
.
Explanation:

Mass of hydrate of copper sulfate = 14.220 g
Moles of hydrate of copper sulfate =
Mass of copper sulfate after heating = 8.9935 g
Moles of copper sulfate = 

Solving for n, we get:
n = 5
The value of n in the hydrate formula is 5 ,
.
