6. 220 mL of oxygen gas was collected over water. The total pressure of oxygen gas plus water vapor was 745.8 mmHg at 25.0°C. What is the pressure, in mmHg, exerted by only the oxygen gas? See Water Vapor Table. 7. A sample of nitrogen gas is collected over water at 20°C and a pressure of 1.00 atm. The volume of the collected gas is 250.0 L. What is the partial pressure of the nitrogen gas? (At 20°C, the vapor pressure of water is 17.5 torr) Dalton's Law: Ptotal = P; nitrogen + Pater Solving this problem: Pnitrogen = Ptotal - Pwater 8. A sample of hydrogen gas is collected over water at 22°C. The pressure of the resultant mixture is 765torr. What is the pressure that is exerted by the dry hydrogen alone?
