Edge length of unit cell of a crystal is 288 pm . If its density is 7.2 ~g ~cm ⁻³ determine the type of unit cell (cat mass =52 ).

Options

  1. AHexagonal cubic
  2. BSimple cubic close
  3. CFace centered cubic
  4. DBody centered cubic

Correct answer

D. Body centered cubic

Step-by-step solution

d= Z M V N_A aligned & 7.2= Z 52 (2.88 10⁻⁸ )^3 6.02 10²³ & Z=1.991 2.0 aligned Therefore, solid has BCC structure.
