Gravimetric Problems A 516.7-mg sample containing a mixture of K,SO, and (NH,)SO, was dissolved in water and treated with Baci,, precipitating the SO, ion as Baso,. The resulting precipitate was isolated by filtration, rinsed free of impurities, and dried to a constant weight, yielding 863.5 mg of BaSO,. What is the %w/w K,SO, in the sample?
