A516.7 mg sample containing a mixture of K2SO, and (NH4)2S0, was dissolved in water and treated with BaCl2,precipitating the S042- as BaSO4. The resulting precipitate was isolated by filtration, rinsed free of impurities, and dried to a constant weight, yielding 863.5 mg of BaSO4. What is the %w/w K2SO4 in the sample?
