A student analyzes a solid salt blend recovered from a thermal-storage system. The blend contains only \(\text{NaCl}\), \(\text{KCl}\), and \(\text{KNO}_3\). Separate representative portions of the blend, each with a mass of \(3.085\text{ g}\), are analyzed as shown below.

Analysis	Procedure	Measured result
Precipitation	The portion is dissolved, excess \(\text{AgNO}_3\text{(aq)}\) is added, and the precipitate is dried.	\(4.305\text{ g}\) of \(\text{AgCl(s)}\)
Thermal decomposition	The portion is heated until only \(\text{KNO}_3\) decomposes and the mass becomes constant.	Final mass of \(2.925\text{ g}\)

The relevant processes are

\[ \text{Ag}^{+}\text{(aq)}+\text{Cl}^{-}\text{(aq)}\rightarrow\text{AgCl(s)} \]

and

\[ 2\,\text{KNO}_3\text{(s)}\rightarrow 2\,\text{KNO}_2\text{(s)}+\text{O}_2\text{(g)}. \]

The relevant molar masses are \(M_{\text{NaCl}}=58.5\text{ g mol}^{-1}\), \(M_{\text{KCl}}=74.5\text{ g mol}^{-1}\), \(M_{\text{KNO}_3}=101.0\text{ g mol}^{-1}\), \(M_{\text{AgCl}}=143.5\text{ g mol}^{-1}\), and \(M_{\text{O}_2}=32.0\text{ g mol}^{-1}\). Which of the following gives the mole-percent composition of the original blend in the order \(\text{NaCl}\), \(\text{KCl}\), and \(\text{KNO}_3\)?
