The molar conductivities at infinite dilution for NaI, `CH_(3)COONa` and `(CH_(3) COO)_(2)` Mg are `126.9 , 91.0` and `187.8 S cm^(2) mol^-1` respectively at `25^(@)` C . What is the molar conductivity of `Mgl_(2)` at infinite dilution ?

Explanation

To find the molar conductivity of MgI₂ at infinite dilution, we will use Kohlrausch's law, which states that the molar conductivity of an electrolyte at infinite dilution is the sum of the molar conductivities of its constituent ions.

### Step-by-Step Solution:

1. **Identify the dissociation of MgI₂:**
\[ \text{MgI}_2 \rightarrow \text{Mg}^{2+} + 2\text{I}^{-} \]
