KCl has NaCl type face centred cubic crystal structure and CsF has CsCl type cubic crystal structure. Calculate the ratio of densities of CsF and KCl it is given that the molar mass of CsF is two that of KCl and edge length of KCl unit cell of 1.5 times that for CsF .

NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which r_"Na"^+ and r_"Cl"^- are 95 and 181 pm respectively , where Cl^- is present at the lattice point of face centered cubic unit cell Na^+ ions are located in void and those compounds which have same crystalline structure also have same coordination system in which Na^+ and Cl^- ions are surrounded by certain number of opposite ions respectively. Under high pressure coordination number changes to 8 :8 type from 6 :6 type. What is the number of second nearest neighbours of Na^+ in NaCl crystal ?
