1.0 x 10^-14 = [H3O+][OH-]
Therefore [OH-] = 1.0 x 10^14 / [H3O+]
[OH-] = 1.0 x 10^-14 / [2.5 x 10^-6]
[OH-] = 4.0 x 10^-9
Since you have a greater concentration of H3O+ than OH-, sweat is acidic. I'm sure if you read your book carefully, you would have a much easier time solving problems such as these :) Hope this helps!
