If 'the length of the edge of unit cell of 'NaCl' type compound having cubic structure is 578 pm, what is the density of the compound? (Na= '.23, Cl=35.5, N,=6.023 x 10^23)'

What is edge length of unit cell, if the radius is 75 pm and it crystallises in a body centred cubic structure?

Assertion : If the length of the unit cell of LiCl having NaCl structure is 5.14 Å, the ionic radius of Cl^(-) ion is 1.82 Å. Reason : Anion-anion contact is retained in LiCl structure because anions constitute the lattice.
