What is the total number of atoms in BCC crystal lattice having 1.8 10²⁰ unit cells?

Options

  1. A9.0 10²⁰
  2. B1.8 10²⁰
  3. C3.6 10²⁰
  4. D7.2 10²⁰

Correct answer

C. 3.6 10²⁰

Step-by-step solution

In one BCC crystal unit cell number of atoms (Z)=2 Total number of atoms = Z Number of unit cells aligned & =2 1.8 10²⁰ & =3.6 10²⁰ aligned
