6. A sample of the hydrocarbon hexane has 205.51 g of carbon and 40.33 g of hydrogen. A sample of hexene, a different hydrocarbon, has 113.58 g of carbon with 19.10 g of hydrogen. A sample of an unknown hydrocarbon has 203.91 g of carbon has 28.58 g of hydrogen. Use mass percents and the law of constant composition to prove that all three compounds are different
