here pH could not be 8 as we normally calculate since pH of acid can't be greater than 7 so it will be less than seven here total H+ ion concentration will be 10^-7 from water and 10^-8 from acid so total [H+] = 10^-7 + 10^-8 now you can solve

This is very interesting question....as here we have not to neglect out the concn of h20 means self ionisation of water comes into play
