A single charcoal briquette has a mass of 0.1 kg, and is made upof almost entirely carbon. I want to burn that briquette in air ina sealed oven. When the combustion is complete, the gases in theoven will include CO2, O2, and N2, and the mole fraction of CO2 inthis exhaust is 5%. How much air is needed (before the combustion)?Give your answer as kg, kg mole, and as a volume in m3 . Assumethat p = 1 atm, and T = 400 ËšC
