Question #ade43
1 Answer
Explanation:
So, you know that 20 g of your sparingly soluble salt,
This means that you can determine its molar solubility, i.e. the number of moles of salt that can actually be dissolved in one liter of water. Start by figuring out how many moles of salt you have
This means that its molar solubility will be
In order to be able to calculate its solubility product constant, you need to determine how many moles of
Use an ICE table to help you with that
I.......
C.....
E.....
By definition, the solubility product constant,
Since you know that you can dissolve 0.5 moles in one liter of water,
This means that
The answer is rounded to one sig fig, the number of sig figs you gave for the mass of the salt.
