What is the pressure of the collected gas once you have also corrected for the vapor pressure of the water?
Correct answer: D. 697 mm Hg
- A. 730 mm Hg
- B. 727 mm Hg
- C. 30.0 mm Hg
- D. 697 mm Hg
- E. 760 mm Hg
Explanation
Correcting the previous pressure by subtracting the given amount for the vapor pressure of water at 302 K gives you: 727 mm Hg - 30 mm Hg vapor pressure = 697 mm Hg as the final pressure.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
