How to Calculate Work Done Using Potential Difference?

[JoulesVolts]

Could someone tell me how to solve this question please?

The potential difference between the two terminals on a battery is 9 volts. How much work (energy) is required to transfer 10 coulombs of charge across the terminals.

What is the definition of potential difference or essentially electric potential?

 

[JoulesVolts]

Potential Difference : Difference in electric potential energy between two points that will cause current to flow in a closed circuit

Potential Difference : Difference in electric potential energy between two points that will cause current to flow in a closed circuit

So it can be considered as the work done in moving a charge between two points then. or V=W/Q.
