Resistance of 0.2 M solution of an electrolyte is 50 . The specific conductance of the solution is 1.4 S m-1. The resistance of 0.5 M solution of the same electrolyte is 280
. The molar conductivity of 0.5 M solution of the electrolyte in S m2 mol-1 is :
5 x 10-4
5 x 10-3
5 x 103
5 x 102
Specific conductance,
Resistivity,
Resistance, R=
Now, for a 0.5 M solution, R=280
molar conductivity,
=
Therefore, the correct option is (1).
