Options
- A. 1.223 10^ 23
- B. 3.628 10^ 23
- C. 4.487 10^ 23
- D. 6.022 10^ 23
Answer
D. 6.022 10^ 23
Step-by-step solution
Number of atoms in 0.5 mole of the compound = 0.5 N_A = 0.5 6.022 10^ 23 = 3.011 10^ 23 . In a close-packed structure, the number of tetrahedral voids is twice the number of atoms forming the lattice. Number of tetrahedral voids = 2 3.011 10^ 23 = 6.022 10^ 23 . Answer: 6.022 10^ 23
