The ratio for an mass-to-charge electron is #5.64 x 10^(-12)# kg/C. In another experiment, using Millikan's oil drop apparatus, the found the charge on the electron is #1.605 x 10^(-19)# C. What would be the mass of the electron, according to these data?

We have the ratio #"mass"/"charge"#, and #"charge"#........

And should I multiply #"mass"/cancel"charge"xxcancel"charge"#, I should get an answer of #"mass"#. Let's see:

#5.64xx10^-12*kg*cancel(C^-1)xx1.605xx10^-19*cancelC#

#~=1xx10^30*kg# for a single electron.

Well, I got the units of mass, which is good, however, you can refine the estimate.
