In this problem, we asked to find the density of the cubic unit cell, perovskite (in g/cm3), given the edge length.

When examining the particles within a crystal you may observe them tightly packed in an organized pattern. The smallest portion of which is termed the unit cell

The face-centered cubic unit cell is composed of a cube with one atom at each of its corners and one atom in the center of each cube face


To solve this problem:

Step 1. Determine the formula of the compound.

Step 2. Find the mass of the unit cell.

Step 3. Determine the volume of the unit cell

Step 4. Calculate the density of the unit cell.
