The percent composition of a compound is the calculated measure of each ... A sample of a liquid with a mass of 8.657 grams was discovered into its elements ad gave 5.217 grams of carbon, 0.9620 grams of hydrogen, and 2.478 grams of oxygen. ... mass of oxygen = 2.478 grams ... 14.01 g/mol x100 = 3.03 g/mol x 100.
