How many electrons would have to be removed

Reference no: EM13695538

I'm working on this question out of my book and I'm come to a question that I'm very confused on. I'm not really sure where to even start with it. The question is:

Question: How many electrons would have to be removed from a coin to leave it with a charge of +7.0 x 10^-8 C?

Please show all work and clearly explain how many electrons would have to be removed.
