Vedclass · Answer

(A) Molar conductivity $(\Lambda_m)$ is defined as the conductivity $(\kappa)$ divided by the molar concentration $(C)$: $\Lambda_m = \frac{\kappa}{C}$.The unit of conductivity $(\kappa)$ is $\Omega^{-1} cm^{-1}$ (or $S \ cm^{-1}$).The unit of molar concentration $(C)$ is $mol \ cm^{-3}$.Therefore,the unit of molar conductivity is $\frac{\Omega^{-1} cm^{-1}}{mol \ cm^{-3}} = \Omega^{-1} cm^{2} mol^{-1}$.
