A compound M_(p)X_(q) has cubic close packing (ccp) arrangement of X.

1.	A compound M_(p)X_(q) has cubic close packing (ccp) arrangement of X. Its unit cell structure is shown on the side. The empirical formula of the compound is
Answer» MX `MX_(2)` `M_(2)X` `M_(5)X_(14)` Solution :`"No. of M atoms" = underset(("Edge centre"))(4times1/4) + underset(("Body centre"))1=2` `"No. of atom" = underset("corners")(8times1/8)+underset("face centre")(6times1/2)=4` `therefore "UNIT FORMULA" = M_(2)X_(4)` `therefore "empirical formula" = MX_(2)`
