Calculate the number of atoms in 0.3 gram metal if it forms bec structure [ a ^3=3 10⁻²² ~g ]
Options
- A1.0 10²¹
- B2.0 10²¹
- C3.0 10²¹
- D4.0 10²¹
Correct answer
B. 2.0 10²¹
Step-by-step solution
For bec unit cell, n =2 . No. of particles in x ~g = x n a ^3 Number of atoms in 0.3 g of metal = 0.3 2 3 10⁻²² =2.0 10²¹ atoms
