A substance containing only carbon and hydrogen is analyzed and found to contain 85.7% carbon by mass. A gaseous sample of the substance is found to have a density of 1.87 g/L at STP. a)What is the molar mass of the compound? b)What are the empirical and molecular formulas of the compound? c)What are two possible Lewis structures for molecules of the compound. Hint: In one of the structures C atoms can form a ring (all C atoms are connected to each other)
