A sample of oxygen is collected over water at a total pressure of 592.2 mmHg at 27C. The vapor pressure of water at 27C is 26.7 mmHg. What is the partial pressure of O2?

Dalton's Law of partial pressure tells us that Ptotal = pO2 + pH2O.
How do you find pressure in this case ?
Read the problem.
Ptotal = 592.2 mm
pO2 = 26.7 mm
You're making this a lot harder than it is.
592.2 = 26.7 + pO2
pO2 = 592.2-26.7 = ?
Ptotal = 592.2 mm
pO2 = 26.7 mm
You're making this a lot harder than it is.
592.2 = 26.7 + pO2
pO2 = 592.2-26.7 = ?
