A student is given a mixture of NaCl(s) and NaNO3(s) and is tasked with determining the percent of NaCl in the mixture. The student dissolves 3.613 g of the mixture in 50 mL of DI water. The student then adds excess AgNO3(aq) to precipitate the chloride ion as AgCl(s). The student determines that 2.268 g of AgCl is formed.
