Question
A mixture of propane and butane is fed into a furnace where it is mixed with air. The furnace exhaust leaves the furnace at \(T_3 = 339 \, ^\circ \text{C}, \, P_3 = 786.0 \, \text{mmHg} \) and contains only \( \text{N}_2, \, \text{O}_2, \, \text{CO}_2, \) and \( \text{H}_2\text{O} \). The partial pressure of \( \text{O}_2 \) in the exhaust is \( p_{\text{O}_2} = 10.38 \, \text{mmHg} \), and the partial pressure of \( \text{CO}_2 \) in the exhaust is \( p_{\text{CO}_2} = 85.67 \, \text{mmHg} \). **Diagram Description:** Diagram of a furnace process is presented: - **Inputs to the Furnace:** - \( n_1 \), a mixture of propane (\( \text{C}_3\text{H}_8 \)) and butane (\( \text{C}_4\text{H}_{10} \)) - \( n_2 \), air comprising \( \text{N}_2 \) and \( \text{O}_2 \) - **Outputs from the Furnace:** - Products \( n_3 \) at temperature \( T_3 \) and pressure \( P_3 \), containing \( \text{CO}_2, \, \text{H}_2\text{O}, \, \text{O}_2, \) and \( \text{N}_2 \) **Question:** What is the mole fraction of propane in the fuel stream? **Calculations Box:** A box is provided for the answer, labeled as "mole fraction:" with units \( \text{mol} \, \text{C}_3\text{H}_8 / \text{mol} \).
