Answer:
There are x water molecules in the hydrate
Explanation:
Here, we want to get the number of water molecules present
In writing a hydrate formula, we write the formula of the anhydrous salt first
In this case, the anhydrous salt is copper sulfate
Now, we move on to the hydrate molecule. The number of the water molecules is the first thing, followed by the formula for water
In this case, we have this number as x
Thus, we can conclude that there are x molecules of water in the hydrate
