Cubic Unit Cell Calculator

Find crystal density from a cubic unit cell.

Calculated Output

Density (g/cm³) 8.972

Cell volume (cm³) 0

Formula: density = Z·M ÷ (Nₐ · a³)

Step-by-Step Breakdown

1. Values used:

2. Edge length = 361 pm

3. Atoms per cell = 4

4. Atomic mass = 63.55 g/mol

6. Density = 8.972g/cm³

7. Cell volume = 0cm³

The math behind it

density = (atoms per cell × atomic mass) ÷ (Avogadro's number × edge³). Edge in pm is converted to cm (×10⁻¹⁰).

Copper (FCC, 4 atoms, 361 pm) → ~8.96 g/cm³.
