Vedclass · Answer

(B) The molar conductivity $(\Lambda_m)$ is defined as the conducting power of all the ions produced by dissolving $1 	ext{ mole}$ of an electrolyte in $V 	ext{ mL}$ of solution.It is related to specific conductivity $(\kappa)$ and molarity $(M)$ by the formula: $\Lambda_m = \frac{\kappa 	imes 1000}{M}$.Since specific resistance (resistivity) $X = \frac{1}{\kappa}$,we have $\kappa = \frac{1}{X}$.Substituting this into the formula,we get $\Lambda_m = \frac{1000}{MX}$.

If $X$ is the specific resistance (resistivity) of the solution and $M$ is the molarity of the solution,the molar conductivity of the solution is given by:
