How much carbon dioxide is generated by the combustion of 30g of coal (designate coal as carbon “C”).

C + O2 = CO2
Amount of substance (C) = mass / atomic mass of carbon = 30/12 = 2.5 mol
This means that carbon dioxide was also formed 2.5 mol
1 mol at normal conditions takes 22.4 liters, and 2.5 – 56 liters
