Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these were decomposed the sulfur dioxide produced 3.49g oxygen and 3.50g sulfur, while the sulfur trioxide produced 9.00g oxygen and 6.00g sulfur.
A) Calculate the mass of oxygen per gram of sulfur for sulfur dioxide.
B) Calculate the mass of oxygen per gram of sulfur for sulfur trioxide.
