QUESTION:

Propane fuel \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)\) is burned in the presence of air. Assuming that the combustion is theoretical-that is, only nitrogen \(\left(\mathrm{N}_{2}\right)v, water vapor \(\left(\mathrm{H}_{2} \mathrm{O}\right)\), and carbon dioxide \(\left(\mathrm{CO}_{2}\right)\) are present in the products - determine (a) the mass fraction of carbon dioxide and (b) the mole and mass fractions of the water vapor in the products.
