Given:

$\kappa =2.50\times 10^{-4}{\text{ S cm}}^{-1}$

$C=0.0020\text{ M}$

The molar conductivity ${\Lambda }_m$ is given by the formula:

${\Lambda }_m=\frac{\kappa \times 1000}{C}$

Substituting the given values:

${\Lambda }_m=\frac{2.50\times 10^{-4}\times 1000}{0.0020}$

${\Lambda }_m=\frac{0.250}{0.0020}$

${\Lambda }_m=125{\text{ S cm}}^2{\text{ mol}}^{-1}$

Answer: $125$
