<u>Answer: </u>The mass percentage of sulfur in the given compound is 34.56 %.
<u>Explanation:</u>
We are given:
Mass of carbon in compound = 59.9 g
Mass of oxygen in compound = 24.4 g
Mass of Hydrogen in compound = 21.7 g
Mass of the compound = 162 g
Mass of sulfur in compound = ![162-(59.9+24.4+21.7)=56g](https://tex.z-dn.net/?f=162-%2859.9%2B24.4%2B21.7%29%3D56g)
To calculate the mass percent of an element in a compound, we use the equation:
![\text{Mass percent of sulfur}=\frac{\text{Mass of sulfur in compound}}{\text{Mass of the compound}}\times 100](https://tex.z-dn.net/?f=%5Ctext%7BMass%20percent%20of%20sulfur%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20sulfur%20in%20compound%7D%7D%7B%5Ctext%7BMass%20of%20the%20compound%7D%7D%5Ctimes%20100)
Putting values in above equation, we get:
![\text{Mass percent of sulfur}=\frac{56g}{162g}\times 100 = 34.56\%](https://tex.z-dn.net/?f=%5Ctext%7BMass%20percent%20of%20sulfur%7D%3D%5Cfrac%7B56g%7D%7B162g%7D%5Ctimes%20100%20%3D%2034.56%5C%25)
Hence, the mass percentage of sulfur in the given compound is 34.56 %.
