Question

The conductivity of 0.20 M solution of KCl at 298 K is 0.0248 S cm⁻¹. Calculate its molar conductivity.

Answer 1

κ = 0.0248 S cm−1 and c = 0.20 M

Formula of molar conductivity,

Λm = ( k × 1000) / M

Λm = (0.0248 × 1000) / 0.2

Λm = 124 S cm2 mol−1

Molar conductivity could b e easily calculated based on the different factors that the answer is 124 S cm2 mol−1
