7th Edition 6A.19

In part c, it says the concentration of H3O+ ions is 3.1 M, except in the solutions manual they use 3.1 x 10^-3 to find the concentration of OH- ions. Why is that?

I was also confused about this. I assumed this may have just been an error in the book.

I'm not sure if this helps or not, but I have the 6th edition and this similar problem appears in my textbook but mine says that H3O+ part (c) is 3.1mmol•L^-1 and when converting it to only moles it gives 0.0031 which is 3.1 x 10^-3. If by any chance this helps.
