The van der Waal's constant 'b' for N_2 and H_2 has the values 0.04 lit "mol"^(-1) and 0.025 lit "mol"^(-1) .The density of solid N_2 is 1 g cm^(-3) .Assuming the molecules in the solids to be close packed with the same percentage void, the density of solid H_2 would be (in cm^(-3) )

Three-dimensional close packing in solids is referred to as stacking the second square closed packing exactly above the first. In this tight packing, the spheres are horizontally and vertically correctly balanced. Similarly, we can obtain a simple cubic lattice by adding more layers, one above the other. This can be done in two ways. Three-dimensional close packing from two-dimensional square close-packed layers: By putting the second square closed packing exactly above the first, it is possible to form three-dimensional close packing. In this tight packing, the spheres are horizontally and vertically correctly balanced. Similarly, we can obtain a simple cubic lattice by adding more layers, one above the other.Three-dimensional close packing from two-dimensional hexagonal close-packed layers: With the assistance, of two-dimensional hexagonal packed layers, three-dimensional close packing can be obtained. The coordination number of cubic closed packing is:
