Final answer:

To determine the partial pressure of each gas in the mixture, calculate the mole fraction of each gas and then use the equation Partial Pressure = Mole Fraction × Total Pressure.

Step-by-step explanation:

In order to determine the partial pressure of each gas, we first need to calculate the mole fraction of each gas in the mixture. The mole fraction of a gas is the ratio of the number of moles of that gas to the total number of moles in the mixture.

For N₂, the mole fraction is calculated as:

X₂ = n₂ / (n₂ + nCO)

Similarly, for CO:

XCO = nCO / (n₂ + nCO)

Once we have the mole fractions, we can calculate the partial pressure of each gas using the equation:

Partial Pressure = Mole Fraction × Total Pressure
