    6.178 g.

    Explanation:

    KCl is ionized in the solution as:

    KCl → K⁺ + Cl⁻.

    ∴ [KCl] = [K⁺] = [Cl⁻] = 0.193 M.

    Molarity is defined as the no. of moles of the solute per 1.0 L of the solution.

    ∵ M = [ (mass/molar mass) KCl][ (1000) / (V of the solution) ].

    ∴ mass of KCl = (M) (molar mass of KCl) (V of the solution) / 1000 = (0.193 M) (74.55 g/mol) (430.0 mL) / 1000 = 6.178 g.
