Question- A pure gaseous hydrocarbon has a density of 0.103 lb/cu ft at 14.7 psia and 100 degrees F. Chemical analysis shows that there are two hyrogen atoms for each carbon atom in each molecule. What is the formula of this molecule? Assume that the hydrocarbon acts like an ideal gas.It is not a question in the book, so I just need the full solution of deriving!
