A mixture of 0.220 moles CO,0.350 moles N₂ and 0.640 moles Ne has a total pressure of 2.95 atm.What is the pressure of CO?

Question

Quizplus · Accepted Answer

To find the partial pressure of CO, we need to use the mole fraction of CO in the mixture.
Mole fraction of CO = moles of CO / total moles in the mixture
Mole fraction of CO = 0.220 / (0.220 + 0.350 + 0.640) = 0.183
Now, using Dalton's law of partial pressures, we can find the partial pressure of CO.
Partial pressure of CO = mole fraction of CO x total pressure
Partial pressure of CO = 0.183 x 2.95 atm = 0.536 atm
Therefore, the answer is C) 0.536 atm.
