Solution

The correct option is A 419.05Ccm2eq1
Value of resistance is given, cell constant is given
So from these we can find the specific conductance and from the specific conductance
We will find the equivalent conductivity
R=210ohm.1a=0.88cm1
k=1R×1a=1210×0.88=4.19×103ohm1cm1orScm1
eq=k×1000N=4.19×103×10000.01
=419.05Ccm2eq1
