Calculate the number of atoms in 0.3 gram metal if it forms bec structure [ a ^3=3 10⁻²² ~g ]

Options

  1. A1.0 10²¹
  2. B2.0 10²¹
  3. C3.0 10²¹
  4. 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
