CsBr has bcc structure with edge length 4.3. The shortest interionic distance in between Cs+ and Br− is
CsBr crystallises in a body centered cubic lattice. The unit cell length is 436.6pm. Given that the atomic mass of Cs = 133 and that of Br = 80amu and Avogadro number being 6.02 × 1023 mol−1 the density of CsBr is
How many unit cells are present in 4.0gm of crystal AB (formula mass of AB = 40) having rock salt type structure? (NA = Avogadro's no.)
A molecule A2 B(Mwt. = 166.4) occupies triclinic lattice with a 5Å,b = 8Å, and c = 4Å If the density of AB2 is 5.2 g cm−3, the number of molecules present in one unit cell is
