In a chemistry class, a group of students determined the mass-to-charge ratio for an electron to be 5.64  10-12 kg/C, where C is the change in coulombs. Using Millikan’s oil drop apparatus, this group of students further determined that the charge on the electron is 1.605  10-19 C. Using the data that the students gathered, what is the mass of the electron?
