The solubility product of silver chloride is \(K_{sp}=1.8\times10^{-10}\). In pure water at 25 °C the solubility of AgCl is \(s_0\). (a) Calculate \(s_0\). (b) A 200 mL solution that is saturated with AgCl (i.e., contains \(s_0\) mol L⁻¹ of Ag⁺) is mixed with 200 mL of a \(0.010\ \text{M}\) NaCl solution. Assuming no other sources of Ag⁺, determine the mass (in grams) of AgCl that precipitates on mixing.
