Homework Help: chemistry

Posted by Anonymous on Wednesday, January 13, 2010 at 11:58pm.

Is the calculation of percentage of each atom within a Body centered cubic cell AKA volume of the BCC cell same as the atomic packing factor for the BCC unit cell.

The BCC % is 68%. the atomic packing factor is just 0.68. Am I completely wrong?

And also how do i calculate the lattice constant given Fe is the atom and it's radius is 0.124nm.
I know the lattice constant is a, b, c

would a, b,c be all the same because it's a cube?
