To calculate the molar conductivity (λ_m^∞) of acetic acid (CH₃COOH) at infinite dilution, we will use Kohlrausch's law of independent migration of ions. This law states that the molar conductivity of an electrolyte at infinite dilution is the sum of the molar conductivities of its individual ions. ### Step-by-Step Solution: 1. **Identify the given values**: - Molar conductivity of NaCl (λ_m^∞ NaCl) = 126.45 ohm⁻¹ cm² mol⁻¹ - Molar conductivity of CH₃COONa (λ_m^∞ CH₃COONa) = 91.0 ohm⁻¹ cm² mol⁻¹ - Molar conductivity of HCl (λ_m^∞ HCl) = 426.16 ohm⁻¹ cm² mol⁻¹ ...
