To find the number of lithium atoms in a unit cell, we can use the formula for density and rearrange it to solve for \( Z \) (the number of atoms in the unit cell). Here are the steps: ### Step 1: Write the formula for density The density \( D \) of a substance can be expressed as: \[ D = \frac{Z \cdot M}{A^3 \cdot N_A} \] Where: ...
