to discover pH you do the detrimental log of your concentration, which as a effect is 0.011M. to bypass out of your pH to concentration you will possibly do the antilog(-pH). when you consider which you gave Kb i'm assuming you should discover Ka or something like that. the least confusing equation that i be responsive to for that's (Kb)(Ka) = Kw Kw = a million.0X10^-14
