Calculate the number of unit cells in 0.4 g metal if the product of density and volume of unit cell is 1.2 10⁻²² ~g .

Options

  1. A1.1 10²¹
  2. B2.2 10²¹
  3. C3.3 10²¹
  4. D4.4 10²¹

Correct answer

C. 3.3 10²¹

Step-by-step solution

No. of unit cell in x ~g of metal aligned = x a ^3 & = 0.4 ~g 1.2 10⁻²² ~g & =3.3 10²¹ aligned
