Given concentration $C=0.2$ M and conductivity $k=0.0248{\Omega }^{-1}$ cm${}^{-1}$.

The formula for molar conductivity is ${\Lambda }_m=\frac{k\times 1000}{C}$.

Substituting the given values:

${\Lambda }_m=\frac{0.0248\times 1000}{0.2}$

${\Lambda }_m=\frac{24.8}{0.2}=124{\Omega }^{-1}$ cm${}^2$ mol${}^{-1}$.

Answer: $124{\Omega }^{-1}$ cm${}^2$ mol${}^{-1}$
