I have a neutral object, and the question is asking how many electrons needed to be added to it to give it a charge of -1 C.

After looking at my notes, I was thinking of using the Qnet equation (#e-)(-e) = -1C

so to get (#e-) I plug in 1.602 * 10^-19C and divide -1C by that, to get -1.602 * 10^-19 for number of electrons.

I know this is probably wrong, but I was hoping someone could help clear my confusion. I tried researching this problem and saw a similar question on yahoo answers, but the explanations just answered instead of explaining in detail, and my book doesn't have answers that are quite as similar. I thought the concept was clear enough but the numbers just seem a little weird so I was hoping can someone please clear this confusion?
