\( \mathrm{CsCl} \) has cubic structure of ions in which \( \mathrm{Cs}^{+} \)ion is present in the body centre of the cube. If density is \( 3.99 \mathrm{~g} \mathrm{~cm}^{-3} \). What is the distance between \( \mathrm{Cs}^{+} \)and \( \mathrm{Cl}^{-} \)ions?
(a) \( 356.8 \mathrm{pm} \)
(b) \( 412 \mathrm{pm} \)
(c) \( 128.4 \mathrm{pm} \)
(d) \( 713.6 \mathrm{pm} \)
