<u>Answer:</u> The mass percent of sulfur and oxygen in the compound is 40.05 % and 59.95 % respectively
<u>Explanation:</u>
To calculate the mass percentage of element, we use the equation:
Mass of sulfur = 4.008 g
Mass of compound = 10.008 g
Putting values in above equation, we get:
Mass of oxygen = [10.008 - 4.008] = 6 g
Mass of compound = 10.008 g
Putting values in above equation, we get:
Hence, the mass percent of sulfur and oxygen in the compound is 40.05 % and 59.95 %
