  1. A 182.3
  2. B 258.6
  3. C 288.3
  4. D 364.6
Verified Solution

Answer & Solution

Correct Answer

(B) 258.6

Step-by-step Solution

Detailed explanation

Molar conductivity of \[ \mathrm{Mg}^{2+}\left(\Lambda_{\mathrm{mg}^{2+}}\right)=106 \mathrm{Scm}^2 / \mathrm{mol} \] Molar conductivity of \(\mathrm{Cl}^{\ominus}\) ion \(\left(\Lambda^{\circ}{ }_{\mathrm{Cl}}{ }^{-}\right)\)…
