Calculate the density of metal which forms simple cubic structure with edge length of unit cell 336 pm . (90 gram of meal contains 2.64 10²³ atoms)
Options
- A8.98 ~g ~cm ⁻³
- B10.8 ~g ~cm ⁻³
- C7.3 ~g ~cm ⁻³
- D9.46 ~g ~cm ⁻³
Correct answer
A. 8.98 ~g ~cm ⁻³
Step-by-step solution
aligned d & = Z M V Na & = 1 90 (3.36 10⁻⁸ )^3 (2.64 10²³ ) & = 90 10 (3.36)^3 2.64 =8.98 ~g ~cm ⁻³ aligned
