Question

Alicin contains 59.9 of carbon, 21.7 hydrogen, 24.4 g of oxygen, and sulfur. What the mass percent of sulfur in a 162 g sample of the compound?

Answer 1

34.5 %

Explanation:

The amount of Sulfur in the given amount of Alicin is

162g - ( 59.9 g + 21.7 g +24.4 g)

162g - 106 g

56 g

Mass % of Sulfur = [ mass of Sulfur / mass of compound ] x 100

                       =    56 g x 100 /  162 g

                       =  34.5 %
