55. Solving a chemistry problem

192. The equivalent electrical conductivity of an aqueous solution of propionic acid with a concentration of 0.0039 mol / l at 25 C is 21.7 Ohm-1 mol-1 cm2. Find the degree of dissociation and pH of a solution of propionic acid with a concentration of 0.01 mol/l. The limiting equivalent electrical conductivities of H and CH3CH2COO- ions at this temperature are 349.8 Ohm-1mol-1cm2 and 35.8 Ohm-1mol-1cm2, respectively.
