When a result of barium nitrate and a solution of copper(II) sulphate are mixed a chemical reaction produces solid barium sulphate which sinks to the bottom and a solution of copper(II) nitrate. Presume some barium nitrate is dissolved in 120.00g of water and 8.15g of copper(II) sulphate is mixed in 75.00g of water. The results are poured together and a white solid forms. Subsequent to the solid is filtered off, it is found to have a mass of 10.76g. The mass of the result that passed through the filter is 204.44 g. What is mass of barium nitrate was used in the reaction?
