3.10     The conductivity of sodium chloride at 298 K has been determined at different concentrations and the results                are given below:

 Concentration/M  

0.001   0.010 0.020 0.050

  0.100 

10^{2}\times k/S m^{-1}

 1.237 11.85 23.15 55.53

106.74

 Calculate \Lambda _{m} for all concentrations and draw a plot between \Lambda _{m} and C^{1/2}.Find the value of \Lambda _{m}^{0}.

Molar conductivity is a measure of a solution's ability to conduct electricity. It is calculated by dividing the conductivity of a solution by its molar concentration. The SI unit for molar conductivity is Siemens meters squared per mole.

Limiting molar conductivity is the molar conductivity of an electrolyte solution when its concentration approaches zero, or is at infinite dilution. It is represented by the symbol Λ°m.
