Vedclass · Answer

(B) The relationship between molar conductivity $(\Lambda_m)$ and conductivity $(\kappa)$ is given by the formula: $\Lambda_m = \frac{\kappa 	imes 1000}{M}$.Rearranging for conductivity $(\kappa)$: $\kappa = \frac{\Lambda_m 	imes M}{1000}$.Given: $\Lambda_m = 200 	ext{ } \Omega^{-1} 	ext{ cm}^2 	ext{ mol}^{-1}$, $M = 0.04 	ext{ M}$.Substituting the values: $\kappa = \frac{200 	imes 0.04}{1000}$.$\kappa = \frac{8}{1000} = 0.008 	ext{ } \Omega^{-1} 	ext{ cm}^{-1}$.

The molar conductivity of a $0.04 \text{ M}$ $AB_2$ type salt solution at $300 \text{ K}$ is $200 \text{ } \Omega^{-1} \text{ cm}^2 \text{ mol}^{-1}$. Find the conductivity.
