Explain what is the percentage by mass of barium

Reference no: EM13337760

An ore of barium contains BaCO3. A 1.315 g sample of the ore was treated with HCl to dissolve the BaCO3. The resulting solution was filtered to remove insoluble material and then treated with H2SO4 to precipitate BaSO4. The precipitate was filtered, dried and found to weigh 1.074 g. What is the percentage by mass of barium in the ore? (Assume all of the barium is precipitated as BaSO4.)
