The compound forming ccp structure contains 9.6 10²³ atoms. Find the number of tetrahedral voids formed in it.

Options

  1. A1.00 10²⁴
  2. B1.68 10²⁴
  3. C1.92 10²⁴
  4. D1.56 10²⁴

Correct answer

C. 1.92 10²⁴

Step-by-step solution

The number of tetrahedral voids in a cubic close-packed structure is twice the number of atoms. Given N = 9.6 10²³ atoms, we compute the number of tetrahedral voids as 2 (9.6 10²³) = 19.2 10²³ . Expressed in standard scientific notation, this is 1.92 10²⁴ , which corresponds to option C .
