A mixture of gas (50% nitrogen and 50% oxygen) at 18°C has a volume of 2500 cm3, and initially it is held at the atmospheric pressure Patm = 101.3 kPa. The temperature of the gas mixture is first raised to 37°C using a heater while maintaining the same atmospheric pressure, and then, it is compressed until the gauge pressure is 40 cm H2O while maintaining the same temperature 37°C. What is the partial pressure of oxygen (in absolute pressure) when the gauge pressure is 40 cm H2O? If 40% of the oxygen is replaced by carbon dioxide, find the partial pressure of each gas (nitrogen, oxygen, and carbon dioxide). Assume that the gauge pressure is still 40 cm H2O and the temperature is 37°C.

Question
A mixture of gas (50% nitrogen and 50% oxygen) at 18°C has a volume of 2500 cm3, and initially it is held at the atmospheric pressure Patm = 101.3 kPa. The temperature of the gas mixture is first raised to 37°C using a heater while maintaining the same atmospheric pressure, and then, it is compressed until the gauge pressure is 40 cm H2O while maintaining the same temperature 37°C.
What is the partial pressure of oxygen (in absolute pressure) when the gauge pressure is 40 cm H2O?
If 40% of the oxygen is replaced by carbon dioxide, find the partial pressure of each gas (nitrogen, oxygen, and carbon dioxide). Assume that the gauge pressure is still 40 cm H2O and the temperature is 37°C.
