JEE Main Chemistry question
Resistance of 0.2 M solution of an electrolyte is . The specific conductance of the solution is . If resistance of the 0.4 M solution of the same electrolyte is , its molar conductivity is
Answer: (B)
Solution
Cell constant (from the 0.2 M data). For the 0.4 M solution, \dfrac{cell constant}{R_2}\dfrac{65}{260}$ = 0.25\ \text{S
