$A$ conductivity cell containing $0.001 \ M$ $AgNO_3$ solution develops resistance $6530 \ \Omega$ at $25 \ ^{\circ}C$. Calculate the electrical conductivity of the solution at the same temperature if the cell constant is $0.653 \ cm^{-1}$.

• A
  $1.3 \times 10^{-4} \ \Omega^{-1} \ cm^{-1}$
• B
  $1.5 \times 10^{-4} \ \Omega^{-1} \ cm^{-1}$
• C
  $1.7 \times 10^{-4} \ \Omega^{-1} \ cm^{-1}$
• D
  $1.0 \times 10^{-4} \ \Omega^{-1} \ cm^{-1}$
