Ar crystallizes in fcc arrangement and density of solid and liquid Ar 3.7 and 3 gm/cc respectively. Find percentage of empty space in liquid Ar.

Answer:

Solution:

$\frac{ϕ _{so l i d}}{d _{so l i d}} = \frac{ϕ _{L i q .}}{d _{L i q .}}$

$\frac{0.74}{3.7} = \frac{ϕ _{L i q .}}{3}$

$ϕ_{L i q .} = \frac{0.74 \times 3}{3.7} = 0.6$

$% e m pt ys p a ce = (1 - 0.6) \times 100 = 40%$
