A solid mixture weighing 0.5485g contained merely ferrous ammonium sulfate hexahydrate as well as ferrous chloride hexahydrate. The sample was dissolved in 1 M H2SO4 oxidized to Fe3+ with H2O2 as well as precipitated with cupferron. The ferric cupferron complex was ignited to produce 0.1678g of ferric oxide, Fe2O3 (FM159.69). Compute the weight percent of Cl in the original sample. Ferrous ammonium sulfate heahydrate 392.13 g/mol, ferrous chloride hexahydrate 234.84 g/mol, and cupferron (155.16 g/mol).
