With the complete combustion of propane, 30 l of carbon dioxide was formed. What is the volume of burnt propane (in liters)? Gas volumes are measured under the same conditions.
Reaction equation: C3H8 + 5O2 = 3CO2 + 4H2O
We compose the proportion:
22.4 liters of propane – 3 * 22.4 liters of carbon dioxide
x l of propane – 30 l of carbon dioxide
Solving the proportion, we find: x = 10 liters.
