Question

If the total volume of a simple cubic unit cell is 6.817 × 10^-23 cm³, what is the volume occupied by particles in the unit cell?

• A. 3.57 $\times$ 10$^{-23}$ cm$^3$
• B. 4.57 $\times$ 10$^{-23}$ cm$^3$
• C. 5.57 $\times$ 10$^{-23}$ cm$^3$
• D. 6.57 $\times$ 10$^{-23}$ cm$^3$

Hint:

In a simple cubic unit cell, the volume occupied by the particles is equivalent to the volume of the unit cell. For other structures, account for the number of particles per unit cell.
