56. Solving a chemistry problem

1. The equivalent electrical conductivity of propionic acid at the limiting dilution is 385.6 * 10-4 Ohm-1 * m2 * mol-1 at 25 C, and the ionization constant of this acid is 1.34 * 10-5. Calculate the equivalent electrical conductivity of a 0.05 M propionic acid solution at the same temperature.
