For this we need the molar masses of charcoal (carbon, 12 011 g/mol), propane (C3H8, 44 097 g/mol), and carbon dioxide (CO2, 44 01 g/mol)
[PDF] How much volume does 1 kg of CO2 occupy at room temperature
CO2 has a molecular weight of 44 g/mol 1 kg CO2 = 1000 g × (1 mol/44 g) = 22 7 mol CO2 V=nRT/P, V=(22 7)(0 0821)(300)/1 = 559 L CO2 at 27°C (300K), 1 atm This is a little more than half a cubic meter approximately equal to the volume of two bathtubs or the trunk of a large car
