Calculate the solubility of cux(ksp=[cu2+][x2−]=1.27×10−36) in a solution that is 0.190 m in nacn.

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.

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

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
