Expert Solution

Step 1

Solution:

For every hygroscopic compounds it is always in hydrated form. The percentage of hydrate can be calculated simply by heating the compound upto some degree usually above 100 degree. And the weight difference is recorded.

From that difference we can get the percentage of water and and an impirical formula too.
