2. At 25 C, the dissociation constant of carbonic acid in stage I is 4.510–7 mol*l-1. The limiting molar electrical conductivities of H and HCO3– ions at this temperature are 349.810–4 and 44.510–4 S.m2.mol–1, respectively. The molar electrical conductivity of a solution of a certain concentration is 2.610–4 S.m2.mol–1. Calculate the concentration of the acid.
