We’re being asked to calculate the mass of 1 unit cell when lithium (Li) crystallizes in a body-centered cubic unit cell.

A body-centered cubic (BCC) unit cell is composed of a cube with one atom at each of its corners and one atom at the center of the cube

We’re going to calculate the mass of 1 unit cell using the following steps:

Step 1: Determine how many atoms are present in 1 unit cell.
Step 2: Calculate how many moles is present in the unit cell.
Step 3: Calculate the mass using the molar mass of the atom.
