Determine the density of cesium chloride which crystallises in bcc type structure with the edge length 412.1 pm.The atomic masses of Cs & Cl are 133 & 35.5 respectively. Solution) First calculate the molecular weight of CsCl ..then density = mass / volume. mass of unit cell = molecular mass/avogadro no.volume = (412.1)^3
