EXPLAIN LATTICE CONSTANT IN TERMS OF MOLECULAR WEIGHT AND DENSITY. The lattice constant of a crystal structure (or constants, such as in non-cubic systems) tells you the edge dimension of its unit cell.
This is the distance between the centers of each pair of adjacent atoms lying along the edges of a cubic unit cell. What determines the density of a crystalline material is how much mass each of its atoms has (i.e., its atomic weight), and how close together these bits of mass are packed within a given volume (i.e., the unit cell), which is determined by its lattice constant. In short, the lattice constant and the atomic weight of a material combine to determine its density.
In fact, there's a formula which relates all three: ρ = (n•A)/(V•N) where: ρ = density n = the number of atoms per unit cell A = atomic weight V = the volume of the unit cell, which is determined by the lattice constant (a). ...In cubic systems, V = a³ N = Avogadro's number (6.022 x 10²³ atoms/mol) If this doesn't help, e-mail and I'll send you a diagram.

Formation Of Crystal, Bravais Lattice, Types Of Unit Cells, Solid State Homework Assignment Help, College Chemistry, University Chemistry, Questions On Formation Of Crystal, Formation of Crystal The crystals of the substance are obtained by cooling the liquid (or the melt) of the solution of that substance. The size of the crystal depends upon the rate of cooling.
If cooling is carried out slowly, crystals of large size are obtained because the particles (ions, atoms or molecules) get sufficient time to arrange themselves in proper positions.
