🤓 Based on our data, we think this question is relevant for Professor Tezcan's class at UCSD.

**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?

__PART 1__

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:**

Partial Pressure
