Electric Conductivity

Step 1: Molar conductivity (

%5CLambda_m

) is related to the conductivity (

%5Ckappa

) and the molarity (

C

) by the formula:

%5CLambda_m%20%3D%20%5Cfrac%7B%5Ckappa%7D%7BC%7D

Step 2: Given:

%5Ckappa%20%3D%200.01%20%5C%2C%20%5COmega%5E%7B-1%7D%20%5Ctext%7Bcm%7D%5E%7B-1%7D%2C%20%5Cquad%20C%20%3D%200.5%20%5C%2C%20%5Ctext%7BM%7D

Step 3: Calculate the molar conductivity:

%5CLambda_m%20%3D%20%5Cfrac%7B0.01%7D%7B0.5%7D%20%3D%200.02%20%5C%2C%20%5COmega%5E%7B-1%7D%20%5Ctext%7Bcm%7D%5E2%20%5Ctext%7Bmol%7D%5E%7B-1%7D

Thus, the molar conductivity is:

%5Cboxed%7B0.02%20%5C%2C%20%5COmega%5E%7B-1%7D%20%5Ctext%7Bcm%7D%5E2%20%5Ctext%7Bmol%7D%5E%7B-1%7D%7D
