determine the pH of a 0.116 M Ba(OH)2 solution at 25 degrees C.

i keep getting 13.06 for this answer, but the answer is 13.37 :S

what i do is i take the negative log of the concentration which is 0.9355 which is pOH.

i know that pH = 14 - pOH
so i get pH = 13.06

where am i going wrong ? :S

thanks for help in advance!
