Question

The molar conductivity of a conductivity cell filled with 10 moles of 20 mL NaCl solution is  and that of 20 moles of another identical cell having 80 mL NaCl solution is . The conductivities exhibited by these two cells are same. The relationship between  and  is

Canvas Classes · Accepted Answer

Strategy:
 Use the relation . Since  is constant for both cells, the ratio of molar conductivities is inversely proportional to the ratio of their concentrations.

Step 1: Calculate Concentrations

Step 2: Compare

Step 3: Find the relationship
