What is the [H3O+] for a neutral solution at 50 degrees celsius?
I know that kw=[H3O+][OH] but I am not sure what to do to get the H3O. The value I have for kw=5.76e14 and I have the pH 6.62 but I do not know what the OH would be.

A neutral solution has H3O^+ = OH^ so if the pH = 6.62 then the pOH 6.62
pH = 6.62 = log(H3O^+).
Solve for (H3O^+) 
so I would take the  log of 6.62?

I don't know if I put this in my calculator correctly but I got 0.82.
