Calculate the number of unit cells in 38.6 ~g of noble metal haven density 19 3 ~g ~cm ⁻³ and volume of one unit cell is 6 18 10⁻²³ ~cm ³ ?

Options

  1. A3 236 10²²
  2. B6 180 10²³
  3. C6 236 10²⁰
  4. D3 236 10²³

Correct answer

A. 3 236 10²²

Step-by-step solution

aligned Vol. of metal = Mass Density = 38.6 ~g 19.3 ~g ~cm ⁻³ &=2 ~cm ³ No. of unit cells in 38.6 ~g of noble metal &= Total vol. of metal Vol. of one unit cell &= 2 ~cm ³ 6.18 10⁻²³ ~cm ³ =3.236 10²² aligned
