A mixture containing BaO and CaO weighs 1.82 g. The oxides are converted to the corresponding sulfates, which weigh 3.91 g.  Calculate the percent Ba in the original mixture. Assume that the molecular weights are as follows:   Ba = 137.3 g/mol Ca = 40.08 g/mol BaO = 153.3 g/mol BaSO4 = 233.4 g/mol CaO = 56.08 g/mol CaSO4 = 136.1 g/mol

Question

A mixture containing BaO and CaO weighs 1.82 g. The oxides are converted to the corresponding sulfates, which weigh 3.91 g.  Calculate the percent Ba in the original mixture. Assume that the molecular weights are as follows:

 

  1. Ba = 137.3 g/mol
  2. Ca = 40.08 g/mol
  3. BaO = 153.3 g/mol
  4. BaSO4 = 233.4 g/mol
  5. CaO = 56.08 g/mol
  6. CaSO4 = 136.1 g/mol
