Question

11. 1g of a sample containing NaCl, NaBr and an inert material, with access of AgNO3, produces 0.526 g of precipitate of AgCl and AgBr. By heating this precipitate in a current of Cl, AgBr converted to AgCl and the precipitate then weighed 0.426 g. Then prove that the % of NaCl and NaBr in the sample us 4.25% & 23.2% respectively.
