    = 0.030 M

    Explanation:

    We can take x to be the concentration in mol/L of Ag2SO4 that dissolves

    Therefore; concentration of Ag + is 2x mol/L and that of SO4^2 - x mol/L.

    Ksp = 1.4 x 10^-5

    Ksp = [Ag+]^2 [SO42-]

    = (2x) ^2 (x)

    = 4x^3

    Thus;

    4x^3 = 1.4 x 10^-5

    = 0.015 M

    molar solubility = 0.015 M

    But;

    [Ag+] = 2x

    Hence; silver ion concentration is

    = 2 x 0.015 M

    = 0.030 M
