Answer #1

Major sources of error in determination of molar mass are ;

1. Removing water from outside of flask - as this will give extra mass

2. Ensuring the flask remained sealed and filled with vapour - as if it is not sealed, vapors will escape and mass will decrease .

3 .measuring the mass of condensed liquid

4 . Measuring volume .

These 4 are the sources of error in molar mass determination .

Measuring the temperature and barometric pressure don't have any affect in the molar mass determination .

    Two methods were descibed for determining the volume of the flask used for the molar mass determination. Which method will give a more precise determination of the volume? Why? When two acceptable determinations of the weight of vapor needed to fill the flask have been obtained, remove the foil cover from the flask (do not discard) and clean out the flask. Fill the flask to the very rim with tap water, cover with the foil cover, and weigh the flask,...

    We have already noted two sources of systematic error in the use of this method: not enough sample to displace all the air from the flask and the finite vapor pressure of the unknown. Consider the following possible errors. For each one, describe how the results might be impacted. Please try to be specific (e.g. "The molar mass will be overestimated because...") a. The volume of your flask was found by weighing it, filled with water, at room temperature (20°C)....

    Could someone assist me with this question? In the 19th century, J. B. A. Dumas devised a method for finding the molar mass of a volatile liquid from the volume, temperature, pressure, and mass of its vapor. (next column). He placed a sample of such a liquid in a flask that was closed with a stopper fitted with a narrow tube, immersed the flask in a hot water bath to vaporize the liquid, and then cooled the flask. Find the molar mass...

    Chame nsead tu age 06-17 Experiment 8: Molar Mass of a Volatile Liquid Purpose To determine the molar mass of a pure substance we need to find out (a) the number of moles in a given sample, and (b) the mass of the same sample. Molar mass is then: mass divided by moles Introduction Using the ideal gas equation, PV= nRT, we can determine the number of moles (n) of gas or vapor under measured conditions of pressure (P), volume...
