3 A 250.0 g sample of a white solid is known to be a mixture of N KNO3, BaCl2, and NaCl. When 100.0 g of this mixture is dis- solved in water and allowed to react with excess H₂SO4, 67.3 g of a white precipitate is collected. When the remaining 150.0 g of the mixture is dissolved in water and allowed to react with excess AgNO3, 197.6 g of a second precipitate is collected. (a) What are the formulas of the two precipitates? (b) What is the mass of each substance in the original 250 g mixture?
