SUMMARY
The density of silicon can be calculated using its atomic weight and lattice constant. With 8 atoms in a unit cell and a lattice constant of 5.43 Å (5.43 x 10^-8 cm), the density is determined to be 4.99 x 10^22 atoms/cm³. This calculation is straightforward and relies on the conversion of the lattice constant from angstroms to centimeters.
