Final answer:
To find the partial pressure of xenon in the container, we need to calculate the total number of moles of gas in the container. Given the masses of argon and xenon and their molar masses, we can calculate the number of moles of each gas. Using Dalton's law of partial pressures, we can then calculate the partial pressure of xenon.
The partial pressure of xenon is: Partial pressure of xenon = 0.132 * 1.00 atm = 0.132 atm
Step-by-step explanation:
To find the partial pressure of xenon in the container, we first need to calculate the total number of moles of gas in the container. Given that the container has a volume of 120.0 ml and is filled with 30.0 grams of argon and 15.0 grams of xenon, we can calculate the number of moles of each gas using their respective molar masses.
Molar mass of argon (Ar) = 39.95 g/mol
Molar mass of xenon (Xe) = 131.29 g/mol
Number of moles of argon = mass of argon / molar mass of argon = 30.0 g / 39.95 g/mol = 0.751 moles
Number of moles of xenon = mass of xenon / molar mass of xenon = 15.0 g / 131.29 g/mol = 0.114 moles
Now, we can calculate the partial pressure of xenon using Dalton's law of partial pressures.
Partial pressure of xenon = mole fraction of xenon * total pressure
Mole fraction of xenon = number of moles of xenon / total number of moles = 0.114 moles / (0.751 moles + 0.114 moles) = 0.132
Given that the total pressure is 1.00 atm, the partial pressure of xenon is: Partial pressure of xenon = 0.132 * 1.00 atm = 0.132 atm
