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.

The number 1.079 × 10⁵ has a certain unit associated with it.  If you can find that, you can figure out what units the final answer is in (recall unit analysis if that doesn't make sense)

Need anything else?  Let us know.
