Answer 2

I believe you will have to use the formulas for equivalent conductance Λ, and the cell constant K.
\[\Lambda = \frac{1000\kappa}{c}\]
\[K = R\kappa\]
Because c can also be written as amount ionized multiplied by the solution (0.02*0.1) you will end up with the following formula:
\[R=\frac{1000K}{\Lambda\cdot0.02\cdot0.1}\]
Since the cell constant K and the equivalent conductance Λ are given, you should be able to solve this question now. :)
