Question
One variety of household fuel is a mixture of propane (60%) and butane (40%). If 20 litres of this mixture is burnt, find the total volume of carbon dioxide added to the atmosphere. The combination reactions can be represented as:
\[\ce{C3H8 + 5O2 -> 3CO2 + 4H2O}\]
\[\ce{2C4H10 +13O2 -> 8CO2 + 10H2O}\]
Solution
Mixture contains 12 lit of propane and 8 lit of butane
Carbon dioxide released by propane is 36 lit
Carbon dioxide released by butane is 32 lit
Total volume of carbon dioxide added to the atmosphere is 68 lit.
