Write expression for molar mass, M ( in kgmol^(-1) )of a body-centred

1.	Write expression for molar mass, M ( in kgmol^(-1) )of a body-centred cubic crystal of an ionic compound if it has an edge length of'a' metre and a density of 'd' kg m^(-3)
Answer» Solution :`d = (Z xx M)/( a^(3) xx N_(A)) or M = dxx a^(3) xx N_(A)`(as for ionic compound having BCC structure , Z =1)
