When a solution of barium nitrate as well as a solution of copper (II) sulfate are mixed, a chemical reaction produces solid barium sulfate as well as an aqueous solution of copper (II) nitrate. An unknown amount of barium nitrate is dissolved in 120.0 g of water as well as 8.15 g of copper (II) sulfate is dissolved in 75.0 g of water. While these solutions are mixed 1.076 g of white solid is isolated as a precipitate by vacuum filtration. The filtrate is found to have a mass of 204.44 g. Explain what mass of barium nitrate was dissolved in the water as well as used for this reaction? Explain the balanced chemical equation and your calculations.
