Potentiometry OH concentration help

In my class we did an experiment using potentiometry and using electrochemical cells to measure Ksp and Kf and im having trouble filling out the table on my lab report first i had to calculate the concentration of CU^2+ by using the meausre Ecell ( 1.15 x 10^2) which i did and then i was asked for the concentration of OH and from that i should be able to calculate Ksp however i dont know how to find the concentration of OH and if someone could point me in the right direction that would be great
Cu(OH)2 (s) --> Cu^2+ (aq) + 2OH (aq)
assume that the initial OH is equal to OH at equilibrium
please let me know if you need anymore info to help

English text is composed of phrases - they start with a capital letter and end with a dot. That tremendously helps in reading.
You must explain the procedure, we have no idea what you did, what you measured, and what is what of what.
