The specific conductance of a saturated solution of silver bromide is k scm^-1. The limiting ionic conductivity of Ag⁺ and Br^- ions are x and y, respectively The solubility of silver bromide in gL^-1 is : (molar mass of AgBr = 188)

• A

  $\frac{\mathrm{\kappa }\times 1000}{\mathrm{x}-\mathrm{y}}$

• B

  $\frac{\mathrm{\kappa }}{\mathrm{x}+\mathrm{y}}\times 188$

• C

  $\frac{\mathrm{\kappa }\times 1000\times 188}{\mathrm{x}+\mathrm{y}}$

• D

  $\frac{\mathrm{x}+\mathrm{y}}{\mathrm{\kappa }}\times \frac{1000}{188}$
