Calculate [H_3O^+] of an aqueous solution that is 8.8 × 10^_10 M in OH. Round your answer to 2 significant figured.
Note: Reference the Fundamental constants table for additional information.
To calculate the concentration of H3O+ from the concentration of OH-, we can use the autoionization constant of water (Kw).
Kw = [H3O+][OH-]
Since Kw = 1.0 x 10^-14 at 25°C, we can rearrange the equation to solve for [H3O+]:
[H3O+] = Kw / [OH-]
[H3O+] = (1.0 x 10^-14) / (8.8 x 10^-10)
[H3O+] = 1.136 x 10^-5 M
Rounded to two significant figures, the concentration of H3O+ in the aqueous solution is 1.1 x 10^-5 M.
