Calculate the volume of air required to burn 100L of propane.
The ethane oxidation reaction is described by the following chemical reaction equation.
C3H8 + 5O2 = 3CO2 + 4H2O;
According to the coefficients of this equation, 5 oxygen molecules are required to oxidize 1 propane molecule. This synthesizes 3 molecules of carbon dioxide.
Let’s calculate the amount of propane available.
To do this, we divide the available gas volume by the volume of 1 mole of ideal gas under normal conditions.
N C3H8 = 100 / 22.4 = 4.46 mol; The amount of oxygen will be.
N O2 = 4.46 x 5 = 22.3 mol;
Let’s calculate the gas volume. To do this, multiply the amount of substance by the volume of 1 mole of gas.
Its volume will be: V O2 = 22.3 x 22.4 = 500 liters;
Taking into account the oxygen content in the air of 21%, the required air volume will be:
V air = 500/0, 21 = 2 381 liters;
