Calculate the molar mass of metal having density $22.24 g cm^{- 3}$ , crystallizes to form unit cell containing 4 particles. $(a^{3} = 5.6 \times 1 0^{- 23} cm^{3})$

Options:

Answer:

Solution:

$d = \frac{Z \times M}{V \times N _{A}} = \frac{4 \times M}{5.6 \times 1 0 ^{- 23} \times 6.02 \times 1 0 ^{23}}$ or $22.24 = \frac{4 \times M}{5.6 \times 6.02}$ $M = 187.43 g / mol$
