A container holds three gases: helium, argon, and xenon. The partial pressures are 0.450 atm helium and 0.350 atm argon. The total pressure is 3.00 atm. What is the partial pressure of xenon?
The sum of the partial pressures is equal to the total pressure.
Solution: Determine the sum of the partial pressures of helium and argon, then subtract the sum from the total pressure.
The sum of the partial pressures of He and Ar = 0.800atm.
