Question

What is the hydrate formula for something that is 0.0243 mol Bal2 and 0.75 mol H2O?

Answer 1

`\text{BaI}_2.30H_2O`

Step-by-step 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:

`(0.75)/(0.0243)\text{ =}30`

The hydrate formula is thus:

`\text{BaI}_2.30H_2O`
