Work equal to 136.0 Joules is expanded in moving 8.5*10^18 electrons between two points in an electric circuit. What potential difference does this estabilish between the two points?

P.S I have the general idea in my head but I think I'm using the wrong approach/method.

The relevant equation to consider is the following:$$W=Q \Delta V$$where W is work; Q is the total charge; and ∆V is the potential difference.  You should recognize that the problem only tells you how many electrons were moved, not the total charge (coulombs).
