Practice question

The conductivity of a 0.01 M LiNO₃ solution is 0.00135 S cm⁻¹. What is the molar conductivity?

Choose one · Correct answer highlighted

67.5 S cm² mol⁻¹ 135 S cm² mol⁻¹ Correct 270 S cm² mol⁻¹ 13.5 S cm² mol⁻¹

Lambdam = (kappa × 1000/c) = (0.00135 × 1000/0.01) = 135 S cm² mol⁻¹ .
