Malone · Answer 1

if you have 1.27*10^-36 = [Cu2+][X2-] then you can set both those values equal to x because they're stoichimetrically equal.

1.27*10^-36=x^2

Take the square root of both sides.

1.13*10^-18=x

That would be your solubility.

Aria Delgado · Answer 2

Solubility = 2.58*10^-18M

Explanation:

Ksp = (Cu^2+) (x)

X = (1.27x10^-36) / 0.190

X = 6.68*10^-36moles/litre

Solubility = Sqrt (6.68*10^-36)

Solubility = 2.58*10^-18M
