Chapter 1, Problem 38AP
In a reproduction of the Millikan oil-drop experiment, a student obtains the following values for the charges on nine different oil droplets.
(a) Based on these data alone, what is your best estimate of the number of electrons on each of the above droplets? (Hint: Begin by considering differences in charges between adjacent data points, and see into what groups these are categorized.)
(b) Based on these data alone, what is your best estimate of the charge on the electron?
(c) Is it conceivable that the actual charge is half the charge you calculated in (b)? What evidence would help you decide one way or the other?

I Can you help me understand how I'm supposed
to find the predictions of the following solutions?
I know this is an Ionic compound and that
the more ions in a solution means it is able
to carry a charge, right?
