How many excess electrons does an object with a total charge of 1.0 x 10exp9C have on it? This is approximately the amount of charge involved in commonly encountered static electricity.

Divide the charge by the charge on one electron.

So if one electron is 1.6 x 10 exp 19 C it would be 1.0 x 10exp9C divided by 1.6 x 10 exp 19 C correct?
