  1. Question 1

    Q1. The conductivity of a 0.1 M NaCl solution is 1.06 × 10⁻² S/cm. Calculate the molar conductivity.

    • A) 106 S cm²/mol
    • B) 10.6 S cm²/mol
    • C) 1.06 S cm²/mol
    • D) 0.106 S cm²/mol

    Answer: 106 S cm²/mol

    Explanation: Λm = κ / c = (1.06 × 10⁻² S/cm) / (0.1 mol / 1000 cm³) = 106 S cm²/mol.
