7th Edition Question 6B.9

Its given that the concentration of H3O+ ions is 1.5 mol/L. When I try to find the concentration of OH- ions by doing (1*10^-14)/(1.5) I get 6.6*10^-15 which is not the right answer. What am I doing wrong?

Technically, this is correct, because the H3O+ concentration is much higher than what it would normally be. This would probably mean this is a very strong acid (or a superacid) that can dissociate completely. Therefore, the OH- concentration is almost nothing. It's possible that the answer on the back of the book is wrong.
