Consider a sample of a hydrocarbon (a compound consisting of only carbon and hydrogen) at 0.959 atm and 298 K. Upon combusting the entire sample in oxygen, you collect a mixture of gaseous carbon dioxide and water vapor at 0.755 atm and 375 K. This mixture has a density of 0.6955 g/L and occupies a volume eight times as large as that of the pure hydrocarbon. Determine the molecular formula of the hydrocarbon.
