Gas Pressure Calculation in a Propane Tank

What is the total pressure of gas in a propane tank if propane has a partial pressure of 33.1 atm, nitrogen’s is 1.11 atm, and oxygen’s is 0.27 atm?

What is the total pressure of the gas mixture?

Answer:

The total pressure of the gas mixture is 34.48 atm.

According to Dalton's law of partial pressures, the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases. In this case, we have three gases in the mixture: propane, nitrogen, and oxygen.

The partial pressure of propane is 33.1 atm, the partial pressure of nitrogen is 1.11 atm, and the partial pressure of oxygen is 0.27 atm. To find the total pressure, we simply add these partial pressures together:

Total Pressure = Partial Pressure of Propane + Partial Pressure of Nitrogen + Partial Pressure of Oxygen

Total Pressure = 33.1 atm + 1.11 atm + 0.27 atm

Total Pressure = 34.48 atm

Therefore, the total pressure of the gas in the propane tank is 34.48 atm. This calculation helps us understand the overall pressure inside the tank, ensuring safe and efficient storage of these gases.
