The molar conductivity of sodium acetate, CH₃COONa, is measured as a function of concentration in water at 298 K, and the following data are obtained:

Concentration (M)…………………………….Λ_m (Sm² mol^–1)

0.0005……………………………………………….0.00892

0.001…………………………………………………0.00885

0.005…………………………………………………0.00857

0.01…………………………………………………..0.00838

0.02…………………………………………………..0.00812

0.05…………………………………………………..0.00769

0.1…………………………………………………….0.00728

Is sodium acetate a weak or strong electrolyte? Determine Λ⁰_m using appropriate methodology depending on your answer.
