Alright guys...

Trying to finish this god damn Materials Science homework and I hit a brick wall. I'm looking at this example (the question I have is exactly the same, just different ions and radii, etc), but in this example in the book, they give you the radii as .102 and .181 nm. I have no idea if I missed something, but why the hell do they use .102 and .181 x 10^-7 in the equation? Did something change that? Shouldn't it be x10^-9? Or am I going insane?

Link to example.

nm = 10^-9

You are not insane

Then it's probably a text error.

At least 2 of you agree with me. Text book error already... in Chapter 2 :roll:

Textbook errors are a complete logic / sef-confidence fuck. I hate em!
