Crystalline silicon has a cubic structure. The unit cell edge length is $543 \mathrm{pm}$. The density of the solid is $2.33 \mathrm{~g} / \mathrm{cm}^{3}$. Calculate the number of Si atoms in one unit cell.
Added by Sydney J.
Step 1
First, we need to find the volume of the unit cell. Since it's a cube, the volume is the edge length cubed. We need to convert the edge length from picometers (pm) to centimeters (cm) first: 1 pm = 1 × 10^(-12) m = 1 × 10^(-10) cm Edge length in cm = 543 pm × 1 Show more…
