At \( 300 \, \text{K} \), the molar conductivities of the aqueous solutions of three salts at two different concentrations are given below:
The conductivity of a saturated aqueous solution of AgCl is \( 1.40 \times 10^{-6} \, \text{S cm}^{-1} \) at \( 300 \, \text{K} \). If the solubility of AgCl in water at \( 300 \, \text{K} \) is \( X \, \text{mol L}^{-1} \), then \( \log_{10}\!\left(X^{-1}\right) \) is
(Assume that AgCl dissolved in water ionizes completely and that the molar conductivity of saturated AgCl solution is equal to its limiting molar conductivity.)
