Answer:
[tex]\text{BaI}_2.30H_2O[/tex]
Explanation:
Here, we want to get the hydrate formula
To get the hydrate formula, we need to get the number of molecules of water
Now, to get this, we have to divide the number of moles of water by the number of moles of the anhydrous solid
The number of moles of water is given as 0.75 while that of the anhydrous solid is 0.0243
Mathematically, we have it that:
[tex]\frac{0.75}{0.0243}\text{ =}30[/tex]The hydrate formula is thus:
[tex]\text{BaI}_2.30H_2O[/tex]
