Gravimetric Problems A 0.6812-g sample of a mixture consisting of NaBr, Nal, and NaNO, was analyzed by adding AGNO, to precipitate the Br – and I-, yielding a 1.1086-g mixture of AgBr and Agl. The precipitate was then heated in a stream of C12, converting it to 0.8125 g of AgCl. Calculate the %w/w NANO3 in the sample.
