Intermolecular_Forces__Liquids_and_Solids : DensityFromUnitCell (13 Variations)


Oldhamite (CaS) has a rock salt structure like NaCl (which has interpenetrating face-centered cubic structures). The ionic radius of Ca2+ is 0.99 angstroms, and the ionic radius of S2- is 1.84 angstroms. What is the density of CaS?
