Chapter 11, Problem 11.133QP
In an experiment, 20.00 L of dry nitrogen gas, N2, at 20.0°C and 750.0 mmHg is slowly bubbled into water in a flask to determine its vapor pressure (see the figure on next page).
The liquid water is weighed before and after the experiment, from which the experimenter determines that it loses 353.6 mg in mass. Answer the following questions.
- a How many moles of nitrogen were bubbled into the water?
- b The liquid water diminished by how many moles? What happened to the liquid?
- c How many moles of gas exit the flask during the experiment? What is the partial pressure of nitrogen gas exiting? The total gas pressure is 750.0 mmHg.
- d From these data, calculate the vapor pressure of water at 20°C. Does this agree with what you expect?
