Answer:
Ksp = [ Cu+² ] [ OH-] ²
molar mass Cu(oH )2 ==> M= 63.546 (1) + 16 (2) + 1 (2) = 97.546 g/mol
Ksp = [ Cu+² ] [ OH-] ²
Ksp [ cu (OH)2 ] = 2.2 × 10-²⁰

Ksp = [ Cu+² ] [ OH-] ²
2.2 ×10-²⁰ = (S)(2S)²= 4S³
![s = \sqrt[3]{ \frac{2.2 \times {10}^{ - 20} }{4} } = 1.8 \times {10}^{ - 7}](https://tex.z-dn.net/?f=s%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2.2%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%2020%7D%20%7D%7B4%7D%20%7D%20%20%3D%201.8%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%207%7D%20)
S = 1.8 × 10-⁷ M
The molar solubility of Cu(OH)2 is 1.8 × 10-⁷ M
Solubility of Cu (OH)2 =
![Cu (OH)2 = \frac{1.8 \times {10}^{ - 7} mol \:Cu (OH)2 }{1L} \times \frac{97.546 \: g \: Cu (OH)2}{1 \: mol \: Cu (OH)2} \\ = 1.75428 \times 10 ^{ - 5}](https://tex.z-dn.net/?f=Cu%20%28OH%292%20%3D%20%20%5Cfrac%7B1.8%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%207%7D%20mol%20%5C%3ACu%20%28OH%292%20%7D%7B1L%7D%20%20%5Ctimes%20%20%5Cfrac%7B97.546%20%5C%3A%20g%20%5C%3A%20Cu%20%28OH%292%7D%7B1%20%5C%3A%20mol%20%5C%3A%20Cu%20%28OH%292%7D%20%20%5C%5C%20%20%3D%201.75428%20%5Ctimes%2010%20%5E%7B%20-%205%7D%20)
