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)?
Answer & explanation
Correct answer: option 3
Molar Conductance, ΛM = \(\frac{1000 × Κ}{M}\)
138.9 = \(\frac{1000 × Κ}{1.5}\)
\(\frac{138.9 × 1.5}{1000}\) = K
K = 0.208
