K=kR = (6.67 × 10-3 Ω-1 cm-1) (243 Ω ) = 1.62 cm-1.

Q. A conductance cell when filled with $0.5 M K Cl$ solution (conductivity = $6.67 \times 1 0^{- 3} Ω^{- 1} c m - 1$ ) registers a resistance of $243Ω$ . Its cell constant is

$1.62 c m$

$1.62 c m^{- 1}$

$1.62 d m^{- 1}$

$1.62 m^{- 1}$

$K = k R = (6.67 \times 1 0^{- 3} Ω^{- 1} c m^{- 1}) (243Ω) = 1.62 c m^{- 1}$ .
