Question
At 298 K, the limited molar conductivities at infinite dilution of sodium benzoate, hydrochloric acid and sodium chloride are 8.24 × 10⁻³ S m² mol⁻¹, 4.26 × 10⁻² S m² mol⁻¹ and 1.26 × 10⁻² S m² mol⁻¹, respectively. Calculate the limiting molar conductivity of aqueous benzoic acid.

Word Count : 288
To calculate the limiting molar conductivity of aqueous benzoic acid ($\Lambda_m^0 (\text{C}_6\text{H}_5\text{COOH})$), we can use Kohlrausch’s Law of Independent Migration of Ions, which states that the limiting molar conductivity of a weak electrolyte can be calculated from the sum of the limiting molar conductivities of its constituent ions. _________ _________ _____ ___ ____.
