Hi iuchem16! Welcome to PF! :smile:

What is the definition of potential difference, and its relation to potential energy ? :wink:

Show us what you've tried. :smile:

A potential difference of 277 volts will transfer energy of 277 ev per unit charge to the ion.

Take the charge of your ion, multiply by 277 ev, add to 9.88...
