options are
9 M
1x10(-5) M
1 x 10(-7) M
1 x 10(-9) M

To get pH, you take the negative log of your [H+] (or more accurately, [H3O+]. The inverse operation is raising 10 to the negative pH. This gives you [H3O+].

pH= - log [ H+]
thus,
[H+] = antilog (pH)
.... here's a simple way to solve it without using the calculator..
if the pH= 9.00 then the whole number which is 9 will be the negative exponent of the ten multiplier in the scientific notation.. that is to say.. 1x10^(-9) .. gets???

1 x 10(-9) M
pH = -log [h3o+]
therefore
[h3o+] = 10^(-pH)

in calculating of hydrogen ion and hydronium ion are the same .
pH = - log [H +]
[H+] = 10^ -pH
therefore, answer is 1 * 10^(-9) M.

It is simple.[H3O]=1x10(-9) M and [OH] is 1x10(-5)M
K(water)=1x10(-14)=pH+pOH
