Options
- A. 6.340 10^ 21
- B. 7.518 10^ 21
- C. 5.625 10^ 21
- D. 8.492 10^ 21
Answer
B. 7.518 10^ 21
Step-by-step solution
Mass of one unit cell is given by the product of its volume and density. Mass of one unit cell = 6.65 10^ -23 g Total mass of the metal = 0.5 g Number of unit cells = Total mass Mass of one unit cell Number of unit cells = 0.5 6.65 10^ -23 Number of unit cells = 7.518 10^ 21 Answer: 7.518 10^ 21
