Answer:
<h2>9.00 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>9.00 moles</h3>
Hope this helps you
The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).
The pH of a salt solution depends on the nature of the acid and base that forms the salt.
- Salt of a weak acid and a strong base yields a basic solution
- Salt of a strong acid and a weak base yields an acidic solution
- Salt of a strong acid and a strong base yields a neutral solution.
Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.
