A mixture contains Mg(NO,), and KBr. A 1.85 g sample of this mixture is dissolved in water and an excess of NaOH is added, producing a precipitate of Mg(OH),. The precipitate is filtered, dried, and weighed. The mass of the precipitate is 0.515 g. What is the mass percent of Mg(NO,), in the original mixture?
