In a 1.0×10−6 M solution of KOH(aq) at 25 °C, arrange the species by their relative molar amounts in solution.

H2O(the most), OH^-, K^+, H3O^+, KOH(the least)

Explanation:

In a solution, the solvent molecules account for the highest amount of  chemical species present. The solvent molecules are often present in large excess. Since water is the solvent for KOH, water molecules are the most abundant chemical species present.

The ions; OH^-, K^+, H3O^+ are present in the order depicted in the answer above. KOH is the least abundant specie because KOH is ionic and will be split into its constituent ions in water. There will be little or no KOH specie present in the solution.
