Propane (C3H8) is burned in a combustion chamber at a flow rate of 25.50 m3/min with 30.0% excess air. If the propane and air streams enter the chamber at 25.0°C and 1.20 atm (absolute), and the products leave the chamber at 290.0°C and 2.90 atm (absolute), what is the volumetric flow rate of product gas from the chamber? Assume complete combustion and ideal behavior.1. Use the ideal gas law to find the molar flow rate of propane into the combutstion chamber2. What is the molar flow rate of air into the combustion chamber?3. What is the molar flow rate of products leaving the combustion chamber?4. Use the ideal gas law to find the volumetric flow rate of products leaving the combustion chamber
