A sample of a white solid which is having 250.0-gram known to be a mixture of BaCl2, KNO3, and NaCl. When100.0 g of this mixture is dissolved in the 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 the water and allowed to react with excess AgNO3, 197.6 g of a second precipitate is collected.
1. Determine the formulas of the two precipitates?
2. Determine the mass of each substance in the original 250g mixture?
