Academics

A 0.8612 g sample of a mixture consisting of NaBr, NaI, and NaNO3 was analyzed by adding AgNO3 to precipitate the Br and I, yielding a 1.0816g mixture of AgBr and AgI. The precipitate was then heated in a stream of Cl2, converting it to 0.7125 g of AgCl. Calculate the % w/w NaNo3 in the sample.
