    Answer is: the % ionization of hypochlorous acid is 0.14.

    Balanced chemical reaction (dissociation) of an aqueous solution of hypochlorous acid:

    HClO (aq) ⇄ H⁺ (aq) + ClO⁻ (aq).

    Ka = [H⁺] · [ClO⁻] / [HClO].

    [H⁺] is equilibrium concentration of hydrogen cations or protons.

    [ClO⁻] is equilibrium concentration of hypochlorite anions.

    [HClO] is equilibrium concentration of hypochlorous acid.

    Ka is the acid dissociation constant.

    Ka (HClO) = 3.0·10⁻⁸.

    c (HClO) = 0.015 M.

    Ka (HClO) = α² · c (HClO).

    α = √ (3.0·10⁻⁸ : 0.015).

    α = 0.0014 · 100% = 0.14%.
