8) Barium nitrate reacts with aqueous sodium sulfate to produce solid barium sulfate and aqueous sodium nitrate.
Abigail places 20.00 mL of 0.500 M barium nitrate in a flask. She then adds 45 ml of a 0.225M sodium sulfate
solution and the barium sulfate forms. What is the theoretical yield of barium sulfate in grams? You must
write this equation and then balance it before solving for theoretical yield.
