justify it density of a crystal always increases due to substitutinal impurity defect in fcc lattice a occupy corner pos and b occupy face centre if 1 atom of b is missing from 1 of the face centered pts find formula 1- agcl has same str as that of nacl edge length of unit cell of agcl is found to be 555 pm and density is 5.561 g/cm3 find percentage of sites that r unoccupied 2- the intermetallic cpd liag crystallizes in cubic lattice in which both li and ag have c.n 8 then the crystal class is simple cubic
