Molar conductivity is given by ${\Lambda }_m=\frac{\kappa }{c}$

The SI unit of conductivity $\kappa$ is ${\text{S m}}^{-1}$

The SI unit of concentration $c$ is ${\text{mol m}}^{-3}$

Substituting the units, we get:

${\Lambda }_m=\frac{{\text{S m}}^{-1}}{{\text{mol m}}^{-3}}={\text{S m}}^2{\text{mol}}^{-1}$

Answer: ${\text{S m}}^2{\text{mol}}^{-1}$
