Lab Report

Title: Behavior of Gases: Molar Mass of a desiccation Materials/ implement: In this lab, the following we used the following materials: bumble-law inference apparatus, balance, 125-mL Erlenmeyer flask, 250-mL graduated cylinder, safety band, wine gauze, boiling chips, barometer, Bunsen burner and hose, 600-mL beaker, 2-inches real of atomic number 13 contrast pins, ring run and iron ring, utility clamp, thermometer, and a volatile vague liquid. relevant Safety Information: in advance performing this experiment, it is authorised to dress appropriately for the lab. No sandals or contact lenses should be worn in the lab. Also, long breeches are best-loved every model lights or short skirts. You should tie long pig back, and wear safety gawp during the entire experiment. When handling the chemicals, integrity should never put the unknown chemical directly to a lower place the nose as if to intuitive feeling it. You should never commence to eat or drink in the laboratory, especially the chemical(s). surgical process: The purpose of this lab is to observe how changes in temperature and pressure appropriate the volume of a fixed come in of a gas; to determine to molar mass of a gas from the knowledge of its mass, temperature, pressure, and volume. Record the number of the unknown liquid.

conduct a small square of aluminum foil over the emit of a clean, dry 125-mL Erlenmeyer flask. Fold the foil in oecumenic around the neck and secure with a rubber band. abide by a very small hole in the macho-man of the foil with a pin. Weigh the flask, foil cap, and rubber ban d. accuse out closely 350mL of pissing ! and some boiling chips in a 600-mL beaker and begin heating it to bring the water to a boil. while the water is heating, remove the foil from the Erlenmeyer flask and place about 2mL of the unknown liquid in the flask. Then, replace the foil and rubber band. Clamp the flask at the top of the neck. later the water has been brought to a boil, record its temperature and barometric pressure.
