What is the total pressure of a gas mixture that contains hydrogen at 0.45 atm, nitrogen at 0.25 atm, and argon at 0.60atm
According to Dalton's law of partial pressures, the total pressure is the sum of the individual pressures. Therefore,
Ptotal = 0.45 atm + 0.25 atm + 0.6 atm = ??
If a 2L sample of of a gas at STP is placed into an oven and it expands to 2.2L what is the new pressure?
To find the total pressure of a gas mixture, you need to sum up the individual partial pressures of each gas component in the mixture.
In this case, you have three gases: hydrogen, nitrogen, and argon, each with their respective partial pressures.
To get the total pressure, you simply add up the partial pressures of the gases:
Total Pressure = Partial Pressure of Hydrogen + Partial Pressure of Nitrogen + Partial Pressure of Argon.
Therefore,
Total Pressure = 0.45 atm + 0.25 atm + 0.60 atm.
Calculating this sum will give you the total pressure of the gas mixture.
