Q.A conductivity cell has a resistance of $50 \text{ ohms}$ when filled with $0.1 \text{ M } KCl$ and $500 \text{ ohms}$ when filled with $0.02 \text{ M } KCl$ . If the conductivity of $0.1 \text{ M } KCl$ is $1.29 \text{ S m}^{-1}$ , the conductivity of $0.02 \text{ M } KCl$ is:

0.129 \text{ S m}^{-1}

1.29 \text{ S m}^{-1}

0.258 \text{ S m}^{-1}

0.516 \text{ S m}^{-1}

The correct solution involves applying the fundamental concept to derive the final value step by step...
