Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. when samples of these are decomposed, the sulfur dioxide produces 3.45 g oxygen and 3.46 g sulfur, while the sulfur trioxide produces 9.00 g oxygen and 6.00 g sulfur. calculate the mass of oxygen per gram of sulfur for sulfur dioxide. (it has been 2 years so i did this, i need : ( )

To determine the mass of oxygen per gram of sulfur for sulfur dioxide, we simply obtain the ratio of the mass of oxygen and the mass of sulfur produced from the decomposition of sulfur dioxide. All other values given in the problem statement above are just to confuse us that the question is a difficult one. We do as follows:

mass of oxygen per gram sulfur = 3.45 g / 3.46 g
mass of oxygen per gram sulfur = 0.9971 g O2 / g S

It could possibly be beneficial if the experiment is successful.
