Problem- Chromium (III) hydroxide (Cr(OH)_3) is placed in 1.8L of water. At equilibrium the pH was found to be 6.7. Knowing that the solubility constant for iron (III) at a temperature of 25°C hydroxide is 6.3×10^-31, determine the concentration of Cr^3+ (M) in solution as well as the total mass of Cr^3+ (mg) in solution

Cr(OH)_3 <-----> Cr^3+ + 3OH^-

You must illustrate your work in an efficient manner thus I can understand it clearly
