The specific conductance of a saturated solution of \( \mathrm{AgCl} \) is \( 3.40 \times 10^{-6} \mathrm{ohm}^{-1} \mathrm{~cm}^{-1} \) at \( 25^{\circ} \mathrm{C} \). If \( \lambda_{\mathrm{Ag}^{+}}=62.3 \mathrm{ohm}^{-1} \mathrm{~cm}^{2} \) \( \mathrm{mol}^{-1} \) and \( \lambda_{\mathrm{Cl}^{-}}=67.7 \mathrm{ohm}^{-1} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \), the solubility of \( \mathrm{AgCl} \) at \( 25^{\circ} \mathrm{C} \) is
(a) \( 2.6 \times 10^{-5} \mathrm{M} \)
(b) \( 4.5 \times 10^{-3} \mathrm{M} \)
(c) \( 3.6 \times 10^{-5} \mathrm{M} \)
(d) \( 3.6 \times 10^{-3} \mathrm{M} \)
