How much CO2 is emitted from burning 1 kg of charcoal?

C + O2 → CO2 The molar mass of CO2 is equal to 44.01 g/mol. So using the number of moles that we already found we calculate the amount of CO2 in grams. 4163 * 44.01 =~ 183 214 g or 183.2 kg. In conclusion, when you burn 50kg of coal approximately 183.2 kg of carbon dioxide is released. 2 Steve Blumenkranz
