Question:

The conductivity of 0.20 M KCl solution at 298 K is 0.025 S cm-1. Calculate its molar conductivity.

Options:

225.0 S cm2 mol-1

125.0 S cm2 mol-1

325.0 S cm2 mol-1

425.0 S cm2 mol-1

Correct Answer:

125.0 S cm2 mol-1

Explanation:

Molar conductivity, λm = \(\frac{1000 × K}{M}\)

λm = \(\frac{1000 × 0.025}{0.20}\) = 125 S cm2 mol-1
