When it says Lithium crystallizes in a body centered cubic unit cell. what is the mass of one unit cell.... I did my math, but it says I have to multiply by 2. I am confused in why I have to do that? I also have trouble understanding what is a body-centered cubic cell.

Because there are 2 atoms (represented by spheres (more like circles in this drawing)) per unit cell (cube). |dw:1449950546071:dw| It's kinda hard to see (and impossible to draw here) how only 1/8 of each sphere at each corner is INSIDE the cube. The picture i attached is a little better. If you still cant see it, get a styrofoam sphere (from arts and crafts/dollar store) and cut it into 8 equal pieces.

yeah, it's just the angle it's drawn with, if you were to rotate it you would see that only 1/8 of the spheres (any sphere at the corner) are inside the cube.
