Consider a 100mol mixture that is 71.0% methane (CH4) and 29.0% ethane (C2H6). To this mixture is added 20.0% excess air. Of the methane present, 92.40% reacts, 88.90% of which forms carbon dioxide (CO2), and the balance forms carbon monoxide (CO). Of the ethane present, 89.5% reacts, 88.90% of which forms carbon dioxide, and the balance forms carbon monoxide. What is the theoretical amount of oxygen required for the fuel mixture? molesofO2: What amount of air is added to the fuel mixture? moles of air: How many moles of methane are present in the product gas? moles of CH4 : How many moles of ethane are present in the product gas? moles of C2H6 : How many moles of carbon dioxide are present in the product gas? moles of CO2 : How many moles of carbon monoxide are present in the product gas? moles of CO: How many moles of water vapor are present in the product gas? moles of H2O : How many moles of oxygen are present in the product gas? moles of O2 : How many moles of nitrogen are present in the product gas
