Answer:
Explanation:
Hello,
In this case, since the dissociation of aluminum hydroxide is:
The equilibrium expression is:
Thus, given the concentration of hydroxyl ions in the solution, and the 3:1 mole ratio with the aluminum ions, the concentration of those turn out:
Therefore, the solubility product, Ksp turns out:
Regards.
Answer:
C) 14.1 moles
Explanation:
1 mole = 6.02 *10^ 23
8.50 * 10^24 molecules *(1 mole/6.02*10^23 molecules) ≈ 14.1 moles
