**Allicin (C6H10OS2) contains 59.9 g of carbon, 21.7 g of hydrogen, 24.4 g of oxygen, and sulfur. What is the mass percent of sulfur in a 162 g sample of the compound?**

**Answer:**

Not an expert here, but I believe that you need to find the total # of grams for the other elements and then subtract that from the total sample.

59.9+21.7+24.4=106

162-106=60g of sulfur

Then you must make that into a percent.

60/162=.370370 or 37.037%
