4. Experimental Procedure.
a. How many (total) data plots are to be completed for this experiment? Account for each.
b. What information is to be extracted from each data plot?
Provide the IUPAC name of the following molecule. Don't forget to include the proper stereochemistry where appropriate.

On the graph below, plot the volume of rain in milliliters versus its height in centimeters for the 400 mL beaker. Draw a
straight line through the points and label it "400 mL beaker."

Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know?
(see page 276 text) the design of the beaker is a uniform cylinder
the volume of liquid increases evenly with its height
resulting in a linear relationship.
What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the
graph to assist you in answering the question.
4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a
best-fit curve through the points and label it "250 mL Florence flask."
