The solubility of Chromium (II) Hydroxide is .0035g/100mL
- Calculate the solubility product of Chromium (II) Hydroxide.
I know that we have to find Ksp. but i do not understand how to make the Ksp equation to calculate the solubility product, if it is already given to us...

You are not given Ksp, That's what you are to calculate.
You have g/100 Cr(OH)3. Multiply by 10 gives you g/L. Divide by molar mass to get mols/L.
Then plug that into Ksp expression fopr (Cr^3+). That times 3 gives you the (OH^-). Then solve for Ksp. Post your work if you get stuck.
