What is the molar conductivity at infinite dilution for NaCl if the ionic molar conductivities of Na⺠and Cl⻠are 50
Given: What is the molar conductivity at infinite dilution for NaCl if the ionic molar conductivities of Na⺠and Clâ» are 50.1 S cm² molâ»Â¹ and 76.3 S cm² molâ»Â¹ respectively? These values define the system as per NCERT data. Formula: Kohlrausch’s law: Lambda_mâ° = lambda_{Na^{+â° + lambda_{Cl^{-â°. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: Lambda_mâ° = 50.1 + 76.3 = 126.4 S cm² mol^{-1 . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kgâ»Â¹ Kâ»Â¹, m/s²
