the pressure of a mixture of nitrogen carbon dioxide and oxygen is 300 kPa what is the partial pressure of oxygen if the partial pressures of the nitrogen and carbon dioxide are 200 kPa and 48 kPa

Answer 1

To find the partial pressure of oxygen, we first need to add up the partial pressures of all the gases present in the mixture:

Partial Pressure of Nitrogen = 200 kPa
Partial Pressure of Carbon Dioxide = 48 kPa
Partial Pressure of Oxygen = Total Pressure - (Partial Pressure of Nitrogen + Partial Pressure of Carbon Dioxide)

Partial Pressure of Oxygen = 300 kPa - (200 kPa + 48 kPa)
Partial Pressure of Oxygen = 300 kPa - 248 kPa
Partial Pressure of Oxygen = 52 kPa

Therefore, the partial pressure of oxygen in the mixture is 52 kPa.
