1. What conclusions can you come to regarding the accuracy in determining the conversion factor? include a statement about the significant figures in this exercise.

2. Convert the volume of the balloon calculated in part 2 into cubic feet (ft^3). Is where any way to correct for the non-spherical nature of the balloon? Is so how would you do so and what would be the expected result on your measured volume. Do you think that the number of significant figures that you report for your volume is appropriate? Comment on how many significant figures you think this corrected volume should have and if that is the same number of significant figures that you used in your calculation.

3. in your graphical analysis which variable (mass or volume) is the dependaent variable/ why do you think this is the case when you examine the experiment performed? can you descibe a different experiment which would make the other quatity the dependent variable? id so describe what you would measure in this experiment and what you would then graph.

4. if your laboratory partner were to leave the cap off the microcentrifuge tube during the isopropanol density determination then waht error would you predict for you dendity value? would you expect a density determined from the slope od the graphical data to be larger or smaller than the actual density? explain your reasoning.
