Ka/ pKb chem quesion?

Question

the Ka for hypoclorous acid, HOCl is 2.8 x 10 to the -3 @ 25 degrees celsius. What is the value of pKb?

-Also- how do i write this equation for the ionization of HOCl in H2O.

-What is the OH- concentration of a .05 M aqueous solution of HOCl?

My teacher says if i understand this, then I will be able to do the homework, but, I'm not really getting this. if someone could explain this to me in very simple, step by step type-of terms, that'd be awesome, and good karma will shower you. thanks so much.
