Please also include the correct error and how you calculated it. A binary mixture with a total mass of 0.810 ± 0.001 g of BaCl2•2H2O (molar mass = 244.27 g/mol) and Na2SO4 (molar mass = 142.04 g/mol) produces 0.466 ± 0.001 g of BaSO4 (molar mass = 233.39 g/mol); BaCl2•2H2O is the limiting reactant. The total mass of 0.810 ± 0.001 g contains both of the salts in unknown amounts. Calculate the percent of BaCl2•2H2O and the percent of Na2SO4...
