Vapor Pressure

Vapor extort and Enthalpy of Vaporization of irrigate I. distinguish of Reagents: a. Water H2O II. Summary of Procedure: b. close a 10 mL graduated piston chamber with ? 7mL if peeing c. Fill a 1000 mL beaker with ? 750 mL of weewee d. change the graduated cylinder into the beaker. Add water to the beaker to completely flood out cylinder. e. Measure the difference between the point of the water in the graduated cylinder and the height of the water in the beaker. f. g. take the barometric pressure in mmHg. soup up the water via Bunsen burner to 80°C. Record the temperature and volume. As the temperature begins to blood teleph whiz line back to 50°C, record the temperature and volume every 5°C. h. Once the temperature reaches 50°C, col the beaker rapidly to 0°C by adding ice. Finish by recording volume and temperature. III. Observations and info atmospherical Pressur e| 769 mmHg| Height of water above crank| 50 mmH2O| Number of moles of air in the graduated cylinder: 5.957 x 10-4 Temperature| Volume| Adjusted Volume| Airs partial(p) Pressure| Water Vapor Pressure| 80°C| 125 mL| 124.8 mL| 105.2 mmHg| 720.3 mmHg| 75°C| one hundred fifteen mL| 114.8 mL| 112.72 mmHg| 712.3 mmHg| 70°C| 100 mL| 99.8 mL| 127.8 mmHg| 697.

Therefore, hexane is more likely to throw its bond to operate a vapor than water IV. In this experiment, I was commensurate to use the Clausius-Clapeyron...If you want to get a right essay, ordering it on our website: BestEssayCheap.com
