a compound contains two elements, sulfur and oxygen. in a sample of the compound, the mass of sulfur is 6.41 grams. the mass of the oxygen is 9.60 grams. what is the percentage composition of the compound
Percent composition is mass of element over mass of compound times 100. 6.41 + 9.60 = 16.01 g of compound, so % composition of sulfur is 6.41/16.01 x100 or 40.0%. % oxygen is 9.60/16.01 x 100 or 60.0%.
