SUMMARY
The empirical formula of the hydrocarbon burned in the problem is determined to be C3H8, which is propane. The total pressure of the gas mixture is 1.200 atm, with a partial pressure of H2O at 0.686 atm. Using the relationship between partial pressures and the number of molecules, the ratio of hydrogen to carbon can be established, leading to the conclusion that the hydrocarbon consists of three carbon atoms and eight hydrogen atoms.
