We are being asked to determine the partial pressure of radon in a container with radon and water given that the partial pressure of water is 1 atm and the total pressure is 780 torr.
The total pressure is given by the equation below:
Part 1. A closed system with a volume of 2.0 L contains radon gas and liquid water, and the container is allowed to equilibrate at 27°C until the total pressure is constant.
What is the partial pressure of radon if the total pressure is 780 torr and the water vapor partial pressure is 1.0 atm?
Part 2. Some helium gas is added to the system, and the total pressure increases to 1.20 atm.
What is the new partial pressure of radon?
