A 0.3867-g sample that contains a mixture of Na2SO4 (142.04 g/mmol) and (NH4)2SO4 (132.14 g/mol) is dissolved in water and treated with BaCl2, precipitating the SO42- as BaSO4 (233.39 g/mol). The resulting precipitate is isolated by filtration, rinsed free of impurities, and dried to a constant weight, yielding 653.3 mg of BaSO4. What is the %w/w Na2SO4 and %w/w (NH4)2SO4 in the sample?
