A sample of CO₂ is collected over water at 23°C. If the total pressure of the sample is 734 torr, what is the partial pressure of the CO₂? The vapor pressure of water at 23°C is 21.2 torr.

Question

Quizplus · Accepted Answer

The partial pressure of CO₂ can be found by subtracting the vapor pressure of water at 23°C (21.2 torr) from the total pressure of the sample (734 torr). Therefore, the partial pressure of CO₂ is 734 torr - 21.2 torr = 712.8 torr, which rounds to 713 torr.
