Gases: Molar Mass Of A Vapor

Behavior of Gases: Molar Mass of a Vapor
The purpose of this science lab is to understand the affect of temperature and pres confident(predicate) affect factors
such as volume on an sum total of gas. With this understanding one flock then find the molar mass of the
fixed amount of vapor. In this lab, the use of Boyles law and Avogadros law combine to engender the
ideal gas equation. With this combined equation PV = nRT, one is adequate to(p) to determine atmosphere,
volume, amount (in grams), or temperature (in Kelvin). If taken further, this equation fuck be used to
determine molar mass as in PV = (m/M)RT.

The equipment used in this experiment is listed as follows:
cxxv mL Erlenmeyer flask
250 mL graduated cylinder
600 mL beaker
2-in. square of aluminium hybridize
balance
barometer
Bunsen burner and hose
pins
rubber band
thermometer
wire gauze
utility clinch
approximately 2mL of inscrutable chemical

Procedure:
The procedure first starts with compacting the one hundred twenty-five mL flask and then placing about .2 mL of the unusual liquid into the flask. Then, taking the 2-in. Square piece of atomic number 13 foil and great dealing it over the opening and neck of the flask.



Then batten down the aluminum foil with the rubber band (may need to fold over multiple times in rule to labour tight fit with rubber band). Next make a pin sized hole in the middle of the aluminum foil that is covering the hole of the flask. Make sure to weigh the flask, cap (rubber band and aluminum foil), and unknown liquid.
Now put down around 350 mL of water into a 600 mL beaker and total it to a boil over top of the Bunsen burner. one time at a boil, place the thermometer into the water in order to shoot an accurate reading of the temperature. Also make sure to record the Barometric pressure by placing the scale neighboring to the table where the experiment is taking place. Next place the flask containing the unknown liquid inside and secure the utility clamp onto it to hold it steady in the boiling water.
