Ksp is the equilibrium expression for the dissolving of a solid. The solid ab2 dissolved with the formula ab2(s)-->a(aq)+2b(aq) so the equilibrium comstant is K=([a][b]^2)/[ab2] and since solids are not put into the equation due to the fact that solids don't really have a concentration, it simplifies to K=[a][b]^2. Since Ksp is is how much solute can dissolve at equilibrium Ksp=[a][b]^2. Molar solubility is just another way of saying molarity so if you make x=a you know that b=2x since there is twice the amount of b than a. With those values for a and b in terms of x you can make Ksp=[x][2x]^2 which means that Ksp=4x^3. I hope that helps. Let me know if anything is unclear.

The Ksp Expression for the given solid in molar solubility terms is; Ksp = 4x³

What is the expression of Molar Solubility?

Ksp is simply defined as solubility product constant and it is the equilibrium expression for the dissolving of a solid.

Now, the solid ab₂ dissolved as shown in the formula;

ab₂(s) → a(aq) + 2b(aq)

Thus, the equilibrium constant is;

Ksp = ([a][b]²)/[ab₂]

Now, since the solids are not put into the equation as a result of not having enough concentration, it can be simplified to;

Ksp = [a][b]².  

Now, Molar solubility another term for molarity and as such it means we will say; x = a

Since b = 2x, there is twice the amount of b than a and as such we can write a and b in terms of x to get;

Ksp = [x][2x]² = 4x³
