STANDARD Chemistry Conductance of Electrolytic Solutions MCQ Question

Type: MCQ-numerical-Medium-Class 12

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

A

1.01 × 10²

B

1.01 × 10³

C

1.01 × 10⁴

D

1.01

Correct Answer

Option A

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.
