Question

The distance between $Na^{+}$ and $Cl^{-}$ ions in NaCl with a density $2.165gcm^{- 3}is$

Answer 1

$d = \frac{Z \times M}{a^{3} \times N_{A}}$

$a^{3} = \frac{Z \times M}{d \times N_{A}} = \frac{4 \times 58.8}{2.165 \times 6.023 \times 10^{23}}$

$a^{3} = 179.5 \times 10^{- 24}cm^{3}$

$a = 5.64 \times 10^{- 8}$ cm or 564 pm

Distance between $Na^{+}$ and $Cl^{-}$

$= \frac{a}{2} = \frac{564}{2} = 282pm$
