A solid mixture weighing 0.5485 g contained only ferrous ammonium sulfate hexahydrate and ferrous chloride hexahydrate. The sample was dissolved in 1M H2SO4, oxidized to Fe3+ with H2O2, and precipitated with cupferron. The ferric cupferron complex was ignited to produce 0.167 8 g of ferric oxide, Fe2O3 (FM 159.69). Calculate the weight percent of Cl in the original sample.
