A mixture contains Mg(NO3)2 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)2. The precipitate is filtered, dried, and weighed. The mass of the precipitate is 0.365 g. What is the mass percent of Mg(NO3)2 in the original mixture?
