Question

Density and edge length of a ccp crystal respectively are 5 g cm -3 and 200 pm. The number of unit cells in its 8 gram is (A) 2 × 1023 (B) 5 × 1023 (C) 8 × 1023 (D) 1.6 × 1023

Tardigrade Admin · Accepted Answer

Correct answer is (a) 2 × 1023

Q. Density and edge length of a ccp crystal respectively are $5 g c m^{- 3}$ and $200 p m$ . The number of unit cells in its $8$ gram is

$2 \times 1 0^{23}$

$5 \times 1 0^{23}$

$8 \times 1 0^{23}$

$1.6 \times 1 0^{23}$

Correct answer is (a) $2 \times 1 0^{23}$
