Question:

Electrolytic conductivity of 0.30 M solution of KCl at 298 K is 3.72 x 10-2 S cm-1. What will be the molar conductance of the solution?

Options:

124 S cm2 mol-1

12.4 S cm2 mol-1

1.24 S cm2 mol-1

1240 S cm2 mol-1

Correct Answer:

124 S cm2 mol-1

Explanation:

Molar Conductance, ΛM = \(\frac{1000 × Κ}{M}\)

ΛM = \(\frac{1000 × 3.72 × 10^{-2}}{0.30}\) = 124 S cm2 mol-1
