Question 10:The conductivity of sodium chloride at 298 K has been determined at different concentrations and the results are given below:
Calculate Λm for all concentrations and draw a plot between Λm and c½. Find the value of Λ°m .
Answer:Steps of table
Divide by 102 to get k/sm–1
Divide by 100 to concert m–1 to cm–1
Now draw the graph between Λm and c½.
At zero concentration value of Λm = 124 so that the value of Λ°m = 124.0 S cm2 mol–1
