Hi, I am doing kapustinkii equation at the moment for a lattice structure.

The equation we have been given ie U= 1.079x10tothepowerof5xVxZ+ + Z-

r+ + r-

I have used the equation for LiCl where the atomic radii are 74+ and 108-(pm) what do I have to do to convert it into KJ? or can I leave the answer as it is? if anyone has a worked example of the use of this equation I would be most pleased.
