CHM 101 American University Exp12 Molar Mass of a Volatile Liquid Lab first solve the pre lab it will be better hand written on the pdf file i wanted finished as soon as possible.then when the prof will send the lab data ill send it to solve the lab osmometer
mass
spectrometry
volatile
Procedure Overview:
A. Preparing the Sample
1. Prepare the ask for the sample.
2. Place the sample in the ask.
Report Sheet
3. Prepare a boiling water bath.
boiling chips
1. Place the ask/sample in the bath.
2. Heat the sample to the temperature of boiling water.
Caution:
B. Vaporize the Sample
3. Measure the mass of the ask/sample.
4. Do it again and again.
C. Determine the Volume
and Pressure of the Vapor
1. Measure the volume of the flask.
2. Record the pressure of the vapor in the ask.
D. Calculations
1. Molar mass from data.
2. Determine the standard deviation and the relative standard deviation
(%RSD).
3. Obtain group data.
