A sample containing NaCl, NaBr, & inert material weighs 1.000 g. Excess of AgNO3 gave a white precipitate consisting of only AgCl and AgBr which weighs 0.5260 g. By heating the precipitate in a current of Cl2 gas, the AgBr (187.78 g/mol) is converted to AgCl (143.32 g/mol) and the precipitate weighs 0.4260 g. Find the % NaCl (58.44 g/mol) and % NaBr (102.909 mol) in the original sample.

Question

A sample containing NaCl, NaBr, & inert material weighs 1.000 g. Excess of AgNO3 gave a white
precipitate consisting of only AgCl and AgBr which weighs 0.5260 g. By heating the precipitate in a current
of Cl2 gas, the AgBr (187.78 g/mol) is converted to AgCl (143.32 g/mol) and the precipitate weighs 0.4260
g. Find the % NaCl (58.44 g/mol) and % NaBr (102.909 mol) in the original sample.
