What is the formula for calculating the packing efficiency of a structure?

Options

  1. APacking efficiency = (Volume occupied by spheres) / (Total volume of the unit cell) × 100%
  2. BPacking efficiency = (Total volume of the unit cell) / (Volume occupied by spheres) × 100%
  3. CPacking efficiency = (Total volume of the unit cell) / (Volume of a single sphere) × 100%
  4. DPacking efficiency = (Volume of a single sphere) / (Total volume of the unit cell) × 100%

Correct answer

A. Packing efficiency = (Volume occupied by spheres) / (Total volume of the unit cell) × 100%

Step-by-step solution

The formula for calculating the packing efficiency of a structure is (Volume occupied by spheres) / (Total volume of the unit cell) × 100%.
