Addition of an excess silver nitrate to a 0.5012 g sample yielded a mixture of AgCl and Agl that weighed 0.4700 g. The precipitate was then heated in a stream of Cl2 to convert the Agl to AgCl. 2 Agl (s) + Cl2 (g) 2 AgCI (s) + 12(g) The precipitate was found to weigh 0.3900 g after this treatment. Calculate the percentages of NH4I and NH4CI, respectively.
