Question

7. A 100.00g sample of the gaseous hydrocarbon ethane is a gaseous hydrocarbon, with 79.89g of carbon and 20.11g of hydrogen. Ethylene is a different gas phase hydrocarbon. A 100.00g sample of ethylene has 85.63g of carbon with 14.37 of hydrogen. A sample of a hydrocarbon has 64.580g of carbon has 5.420g of hydrogen.
a. Use the mass percents and the law of constant composition to prove that all three compounds are different.
b. Prove that ethane and ethylene obey the law of multiple proportions.

Answer 1

I didn't address the problem because the third gas doesn't add to 100 g so it must have something else besides C and H and makes it a non-hydrocarbon. I suggest you proof the problem and repost.
