Question:

Molar conductance of a 1.5 M solution of an electrolyte is found to be 138.9 S cm2 mol-1. What is the specific conductance of the solution (in S cm-1)?

Options:

0.108

0.308

0.208

0.416

Correct Answer:

0.208

Explanation:

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

138.9 = \(\frac{1000 × Κ}{1.5}\)

\(\frac{138.9 × 1.5}{1000}\) = K

K = 0.208
