  1. Question 1

    Q1. The specific conductivity of 0.02 M KCl is 0.0027 S / cm. The molar conductivity is

    • A) 135 S cm² / mol
    • B) 13.5 S cm² / mol
    • C) 1.35 S cm² / mol
    • D) 1350 S cm² / mol

    Answer: 135 S cm² / mol

    Explanation: Λ_m = κ / c = 0.0027 S / cm / 0.02 M × 1000 = 135 S cm² / mol.
