What is the density of an element (At. mass $100 g mol^{- 1}$ ) having BCC structure with edge length $400 pm$ ?

Options:

Answer:

Solution:

$a = 400 pm = 400 \times 1 0^{- 12} m = 400 \times 1 0^{- 10} cm = 4 \times 1 0^{- 8} cm Z = 2 (for BCC) d = \frac{Z \times M}{N _{A} \cdot a ^{3}} = \frac{2 \times 100}{6.022 \times 1 0 ^{23} \times ( 4 \times 1 0 ^{- 8} ) ^{3}} = 5.18 g cm^{- 3}$
