1.	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) xx k//S m^(-1), 1.237, 11.85, 23.15, 55.53, 106.74):} Calculate Lambda_(m) for all concentration and draw a plot between Lambda_(m) and C^(1//2). Find the values of Lambda_(m)^(@).
Answer» Solution :`1 S cm^(-1) = 100 S m^(-1)`. The graph is EXTRAPOLATED to MEET Y-axis. It meets the Y-axis at 124.05. `Lambda_(m)^(@)`= Intercept on Y-axis = 124.05 S `cm^(2) mol^(-1)`
