In order to obtain barium in a form that may be put into solution, the natural sulfate, barytes, is fused with sodium carbonate. A quantity of barytes, containing only pure barium sulfate and infusible matter, is fused with excess pure, anhydrous soda ash. Upon analysis of the fusion mass it is found to contain 11.3% BaSO4, 27.7% Na2SO4 and 20.35% Na2CO3. The remainder is barium carbonate and infusible matter. Calculate: (a) % completion of the conversion of barium sulfate to carbonate and the analysis of the 
fusion mass. (b) Composition of the original barites (c) % excess Na2CO3
