Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. when samples of these are decomposed, the sulfur dioxide produces 3.46 g oxygen and 3.47 g sulfur, while the sulfur trioxide produces 8.25 g oxygen and 5.50 g 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.

For A: The mass of oxygen per gram of sulfur for sulfur dioxide is 0.997 g

For B: The mass of oxygen per gram of sulfur for sulfur trioxide is 1.5 g

Explanation:

The chemical equation for decomposition of sulfur dioxide follows:

We are given:

Mass of sulfur = 3.47 g

Mass of oxygen = 3.46 g

To calculate the mass of oxygen per gram of sulfur, we apply unitary method:

For every 3.47 g of sulfur, 3.46 g of oxygen will form.

So, for 1 gram of sulfur, of oxygen will form.

Hence, the mass of oxygen per gram of sulfur for sulfur dioxide is 0.997 g

The chemical equation for decomposition of sulfur trioxide follows:

We are given:

Mass of sulfur = 5.50 g

Mass of oxygen = 8.25 g

To calculate the mass of oxygen per gram of sulfur, we apply unitary method:

For every 5.50 g of sulfur, 8.25 g of oxygen will form.

So, for 1 gram of sulfur, of oxygen will form.

Hence, the mass of oxygen per gram of sulfur for sulfur trioxide is 1.5 g
