2. Below (a through d) is a list of some errors that could occur during the experiment. For each error, consider the effect on the data that would be obtained and trace the effect through to the calculation of molar mass. Circle whether the calculation will yield a higher or lower value than the actual molar mass. Then explain your reasoning for each case in detail. (Note: assume the sample had a molar mass equal to the result in question 1.) A student removed the sample from the heating bath before the sample liquid had all evaporated. calculation HIGHER than actual LOWER than actual Explanation A student did not dry the outside of the flask after removing it from the water bath to weigh the flask with condensed vapor. calculation HIGHER than actual LOWER than actual Explanation calculation HIGHER than actual LOWER than actual After the heating process, the sample had not yet condensed when the foil caps were switched.

Is there a difference between a homogeneous mixture of hydrogen and oxygen in a 2:1 ratio and a sample of water vapor? Explain.
The mass of the flask (in part A.1) before the sample is placed into the flask, is measured when the outside of the flask is wet. However , in part B 3., THE OUTSIDE OF THE FLASK IDS DRIED BEFORE ITS MASS IS MEASURED. The reported mass of the vapor in the flask will be less than the actual mass of the vapor. True or false
