1. The problem statement, all variables and given/known data

A plate carries a charge of -3.0 uC, while a rod carries a charge of +2.0 uC. How many electrons must be transferred from the plate to the rod, so that both objects have the same charge?


3. The attempt at a solution

-2.0 uC / -1.6 x 10^-10 = 1.25 x 10^19 electrons

The wording of this question kinda throws me off. appreciate the help!

Your number of 2C is the correct charge, but there is an error in your charge/electron number. Otherwise you are doing it correctly.
