How can I calculate a pH of hypochlorite buffer into LiCLO with only initial concentrations and no Ka value?
[CLO-]=.1M
[LiCLO]=.1M

Are you allowed to look up the value for Ka for HClO? If so that makes it easy. If not that presents a problem but I would do it this way.
pH = pKa + log(base)/(acid)
pH = pKa + log 0.1/0.1
pH = pKa + log 1
pH = pKa + 0
pH = pKa.
I may not have understood the question; you may wish to post the entire problem.

Yes, I can use the Ka of HClO. (hypochlorite ion from hypochlorous)
HClO is a weak acid with a Ka of 2.9*10-8
The pKa = 7.54 (-log of the Ka)
Since the concentration ratio is equal to 1 and the log of 1 is zero, the pH would equal the pKa.
