A sample of O2(g) is saturated with water vapor at 27 C. The total pressure of the mixture is 772 torr, and the vapor pressure of water is 26.7 torr at 27 C. What is the partial pressure of the O2?

2 answers

The total pressure is 772 torr and the water vapor is 26.7 torr so 772 - 26.7 = 754.3 torr
So partial pressure = 754.3
