Question:

The specific conductance of 0.01 M solution of KCl is 0.0014 Ω-1 cm-1 at 25oC. What will be its molar conductance (Ω-1 cm2 mol-1) ?

 

Options:

140

14

1.4

0.14

Correct Answer:

140

Explanation:

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

                             ΛM = \(\frac{1000 × 0.0014}{0.01}\) = 140 Ω-1 cm2 mol-1
