Analysis OF FCC Unit Cell || Density OF Unit Cell

The silver perchlorate benzene complex, AgClO_(4).C_(6)H_(6) is orthorhombic with unit cell dimensions a_(0)=7.96,b_(0)=8.34 and ,c_(0))=11.7 Å . The formula weight is 285 and there are four molecules per unit cell. Calculate the density of the crystal.

Analysis OF Unit Cells || Density OF Crystal Lattice

Density of a unit cell is respresented as rho = (" Effective no. of atoms (s)" xx "Mass of a unit cell ")/("Volume of a unit cell ")=(Z.M)/(N_(A).a^(3)) where , mass of unit cell =mass of effectuive no . of atoms(s) or ion (s). M= At . mass// formula N_(A) = Avogadro' s no . rArr 6.0323 xx 10^(23) a= edge lemght of unit cell The density of KBr is 2.75 g //cm^(-3) . The length of the edge of the unit cell is 645 pm .To which type of cubic crystal , KBr belongs ?
