    Usually, I don't really do homework problems, but I'm in a good mood. So let's go.

    pH by definition is the -log [H]

    [H] = conc of hydronium ion

    so a pH of 3 would indicate that the [H] is 0.001.

    neutral water's pH is 7... which would indicate that [H] is 0.0000001.

    hope that helps.
