Answer: 0.5 atm
Explanation: To calculate the partial pressure of carbon dioxide, we need to use the mole fraction of carbon dioxide and the total pressure of the container.
The mole fraction of carbon dioxide is:
X(CO2) = n(CO2) / n(total)
X(CO2) = 0.5 moles / (0.5 moles + 0.32 moles + 0.2 moles)
X(CO2) = 0.4762
The partial pressure of carbon dioxide is:
P(CO2) = X(CO2) * P(total)
P(CO2) = 0.4762 * 1.05 atm
P(CO2) = 0.5 atm (rounded to one decimal place)
Therefore, the partial pressure of carbon dioxide in the container is 0.5 atm.
