I am also having problems understanding how to complete this problem, any help would be greatly appreciated.

Two capacitors are identical, except that one is empty and the other is filled with a dielectric ( = 4.20). The empty capacitor is connected to a 18.0 V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric such that it stores the same amount of electrical energy as the empty capacitor?
_________ V
