Calculation of the Amount of Phosphorus Pentoxide (P2O5) Produced

To calculate the amount of phosphorus pentoxide (P2O5) that can be produced in the reaction between oxygen and phosphorus, we need to know the stoichiometry of the reaction. The balanced equation for the reaction is:

4P + 5O2 → 2P2O5

According to the balanced equation, 4 moles of phosphorus react with 5 moles of oxygen to produce 2 moles of phosphorus pentoxide.

To determine the amount of phosphorus pentoxide that can be produced, we need to convert the volume of oxygen (56 liters) to moles using the ideal gas law. The ideal gas law equation is:

PV = nRT

Where: P = pressure of the gas V = volume of the gas n = number of moles of the gas R = ideal gas constant T = temperature in Kelvin

Since the pressure and temperature are not provided in the question, we will assume standard temperature and pressure (STP) conditions, which are 1 atmosphere of pressure and 273 Kelvin.

Using the ideal gas law, we can calculate the number of moles of oxygen:

n = PV / RT

At STP, the ideal gas constant (R) is approximately 0.0821 L·atm/(mol·K).

Let's calculate the number of moles of oxygen:

n = (56 L) / (0.0821 L·atm/(mol·K) * 273 K) n ≈ 2.26 moles

According to the stoichiometry of the reaction, 5 moles of oxygen react with 4 moles of phosphorus to produce 2 moles of phosphorus pentoxide.

Since we have 2.26 moles of oxygen, we can calculate the amount of phosphorus pentoxide produced using the stoichiometry:

(2 moles P2O5 / 5 moles O2) * 2.26 moles O2 ≈ 0.904 moles P2O5

Therefore, approximately 0.904 moles of phosphorus pentoxide (P2O5) can be produced in the reaction.

Please note that this calculation assumes ideal conditions and a complete reaction. In practice, the actual yield may be lower due to various factors such as side reactions and incomplete conversion.
