What parameter(s) can be determined to calculate the density of a crystal from X-ray diffraction data?

Options

  1. ADensity (d) and the number of atoms in the unit cell (z)
  2. BMass of the unit cell (m) and the edge length of the unit cell (a)
  3. CMolar mass (M) and Avogadro's number (N A)
  4. DEdge length of the unit cell (a) and the mass of a single atom (m)

Correct answer

D. Edge length of the unit cell (a) and the mass of a single atom (m)

Step-by-step solution

To calculate the density of a crystal from X-ray diffraction data, you need to know the edge length of the unit cell (a) and the mass of a single atom (m).
