A mixture of propane and butane is burned with pure oxygen. Thecombustion products contain 46.7 mole% H2O. After allthe water is removed from the products, the residual gas contains68.8 mole% CO2 and the balance O2
a. What is the mole percent of propane in the fuel?
b. It now turns out that the fuel mixture may contain not onlypropane and butane but also other hydrocarbons. The fuel does notcontain oxygen. However, the dry combustion gases still contain68.8% carbon dioxide. We wish to determine the elementalcomposition (carbon and hydrogen molar percentages) of the fuelfeed.
(Hint: Calculate the elemental compositions on an oxygen freebasis). What is the mole% of carbon in the fuel?
