STANDARD Chemistry Conductance of Electrolytic Solutions MCQ Question
Specific conductance of 0.1 M NaCl solution is 1.01 × 10⁻² ohm⁻¹ cm⁻¹. Its molar conductance in ohm⁻¹ cm² mol⁻¹ is
1.01 × 10²
1.01 × 10³
1.01 × 10⁴
1.01
Correct Answer
Detailed Explanation
Molar conductance (Λₘ) is calculated using the formula Λₘ = κ × 1000 / M, where κ is the specific conductance and M is the molarity. Substituting the given values, Λₘ = 1.01 × 10⁻² × 1000 / 0.1 = 1.01 × 10² ohm⁻¹ cm² mol⁻¹.
