Question

The degree of dissociation of a weak acid is 0.1, and its molar conductivity at infinite dilution is 380 S cm² mol⁻¹. What is its molar conductivity at that concentration?

Options

Choose one · Correct answer highlighted

380 S cm² mol⁻¹ 190 S cm² mol⁻¹ 76 S cm² mol⁻¹ 38 S cm² mol⁻¹ Correct

Explanation

α = (Lambdam/Lambdam°) , 0.1 = (Lambdam/380) , Lambdam = 38 S cm² mol⁻¹ .
