Determine the molar conductivities of solutions of three inorganic compounds. Their conductivity was determined by measuring the resistance of a conductivity vessel filled with the measured solution with a concentration of 0.02 moldm3 giving the following results: R(KCl) = 470 , R(CuSO4) = 346 , R(K4[Fe(CN)6]) = 120 . The vessel was calibrated with a 0.02 moldm3 solution of KCl with a specific conductivity of 0.2765 Sm1 .
