Find the concentration of H3O if the pOH of a solution is 11.700:
So far I have: pH= 14.000 pOH which is 14.00011.700=2.300
pH = log[H3)]
2.300 = log[H3O]
Lost after that!!!
Help please.

You're almost there.
log(H3O^+) = 2.3
Set 2.3 up on your calculator. Press the 10^{x} key. And the answer comes out. You should get 0.00501 or 5 x 10^{3} depending upon how you have your calculator set up to display the answer. 
Thanks a lot. I just couldn't get there.
