  1. Question 1

    Q1. The conductivity of a 0.1 M solution of KCl is 1.29 S / m. Calculate its molar conductivity.

    • A) 129 S cm² / mol
    • B) 12.9 S cm² / mol
    • C) 1.29 S cm² / mol
    • D) 1290 S cm² / mol

    Answer: 129 S cm² / mol

    Explanation: Molar conductivity = conductivity * 1000 / M = 1.29 * 1000 / 0.1 = 12900 S cm² / mol, then convert to S cm² / mol.
