The actual numerical value needs to be looked up or experimentally figured out. If its the expression you need just remember this general equation: HA = H+ and A-. So, the equilibrium expression will be Ka = [H+][A-]/[HA].  Don't forget powers based on equation coefficients. aA = bB + cC   so  [B]^b[C]^c/[A]^a
