How many number of tetrahedral voids are formed in 5 ~mol of a...

How many number of tetrahedral voids are formed in 5 mol5 \mathrm{~mol} of a compound having cubic close packed structure? (Choose the correct option)

Options

  1. A3.011×10243.011 \times 10^{24}
  2. B6.022×10246.022 \times 10^{24}
  3. C1.550×10241.550 \times 10^{24}
  4. D3.011×10253.011 \times 10^{25}

Correct answer

B. 6.022×10246.022 \times 10^{24}

Step-by-step solution

As in a ccp unit cell having ' N\mathrm{N} ' number of atoms there are ' 2 N2 \mathrm{~N} ' number of tetrahedral voids, so number of tetrahedral voids formed in a 5 mol5 \mathrm{~mol} of a compound having ccp structure is 5×2×6.022×1023=5 \times 2 \times 6.022 \times 10^{23}= 6.022×10246.022 \times 10^{24} voids.
