Using 6.14 x 10^-5 for Ka for benzoic acid, I obtained 47.8% ionization.
Using 6.5E-5 for Ka I obtained 48.77 which rounds to 48.8% ionization.
okay i dding get 48.8 i got 68...
okay i didn't get 48.8 i got 68...
Do you still have a problem? If so, post your work and let me try to find the error. But since you apparently posted 68% and the data base said it was wrong, you might want to try 48.8.
