Calculate concentration of hydroxide, ammonium ion and hydronium ions.?

Question

At room temperature a 0.0100 M ammonia solution was 4.1% ionized. Calculate conc of hydroxide, ammonium ion and hydronium ions.

The best explanation and working will receive the best answer. Thank you.

Answer 1

4.1% ionization means that 0.00041 M of the 0.0100 M ammonia has been ionized, which means that the hydroxide and ammonium concentrations will be 0.00041 M.

If [OH-] = 0.00041 M, then [H+] = 2.44 * 10^-11
