You probably know the edge length for NaCl but I do not.
mass of NaCl molecule = molecular mass of NaCl/6*10^23
mass of KF Molecule = molecular mass of KF/6*10^23
density of KF = length of KF^3/length of NaCl^3 * (Mass of KF/Mass of NaCl)
note Avagadro's number cancels
Oh, times density of NaCl of course
