Behavior of Gases Molar o f a Vapor Experiment

1/ If an insufficient amount of liquid unknown had been used, how would this have affected the value of the experimental molar mass?

2/ if the flask were not wiped completely dry, how would this derived mass of the gas affect the molar mass?

3/ isobutyl alcohol has a boiling point of 108 C. how would you modify the procedure used in this experiment to determine its molar mass?

4/ five moles (5.0 mol) of hydrogen gas at 0 C are forced into a steel cylinder with a volume of 2.0 L. What is the pressure of the gas, in mmHg, in the cylinder?

Explanation / Answer

1) Air can get in to the test tube and modifiy your experimental data.

2) The gas can mix with water on the wall of test tube and you don
