what is the total pressure of a gas mixture that contains hydrogen at 0.45atm nitrogen at 0.25 atm and argon at 0.60 atm
Add the partial pressures of each gas. The pressures that you listed are called partial pressures. Partial pressure of each gas is the part of the total pressure that is due to that gas.
We find the answer through Dalton's law. The law of partial presure states the total pressure of a gas mixture is the sum of the partial pressure(s). There for we have a formula of:
Pt=P1+P2+P3
Pt=0.45atm + 0.25atm + 0.60atm =
Answer 1.30atm
To find the total pressure of a gas mixture, you need to sum up the partial pressures of each gas component. The partial pressure of a gas is the pressure that the gas would exert if it occupied the entire volume alone at the same temperature.
In this case, you have three different gases: hydrogen, nitrogen, and argon. Each gas has its own partial pressure: hydrogen (0.45 atm), nitrogen (0.25 atm), and argon (0.60 atm).
To find the total pressure, simply add the partial pressures of each gas:
Total Pressure = Partial Pressure of Hydrogen + Partial Pressure of Nitrogen + Partial Pressure of Argon
Total Pressure = 0.45 atm + 0.25 atm + 0.60 atm
Total Pressure = 1.30 atm
Therefore, the total pressure of the gas mixture is 1.30 atm.
