We know that specific conductance = cell constant × conductance ⇒ Cell constant = Resistance × specific conductance =0.0212 × 55 =1.166 cm -1

Q. The specific conductivity of $N /10 K Cl$ solution at $2 0^{\circ} C$ is $0.0212 o h m^{- 1} c m^{- 1}$ and the resistance of cell containing this solution at $2 0^{\circ} C$ is $55 o hm$ . The cell constant is

$2.173 c m^{- 1}$

$1.166 c m^{- 1}$

$4.616 c m^{- 1}$

$3.324 c m^{- 1}$

We know that

specific conductance $=$ cell constant $\times$ conductance

$\Rightarrow$ Cell constant $=$ Resistance $\times$ specific conductance

$= 0.0212 \times 55$

$= 1.166 c m^{- 1}$
