At 300 K , the molar conductivities of the aqueous solutions of three salts at two different concentrations are given below :
| Salt | Concentration (M) | Molar conductivity (S cm2 mol−1) |
|---|---|---|
| NaNO3 | 0.01 | 111 |
| 0.04 | 101 | |
| NaCl | 0.01 | 117 |
| 0.04 | 107 | |
| AgNO3 | 0.01 | 125 |
| 0.04 | 116 |
The conductivity of a saturated aqueous solution of AgCl is $1.40 \times 10^{-6} \mathrm{~S} \mathrm{~cm}^{-1}$ at 300 K . If the solubility of AgCl in water at 300 K is $\boldsymbol{X} \mathrm{mol} \mathrm{L}^{-1}$, then $\log _{10}\left(\boldsymbol{X}^{-1}\right)$ 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.)
