How do you find the amount of excess electrons?

Divide the total excess charge by the known charge of a single electron. Continuing with the example above, 2.4 x 10^-18 divided by 1.60 x 10^-19 is the same as 2.4 / 1.60 times 10^-18 / 10^-19. Note that 10^-18 / 10^-19 is the same as 10^-18 * 10^19, which equals 10. 2.4/1.6 = 1.5.
