Question
A compound MpXq has cubic close packing (ccp) arrangement of X. Its unit cell structure is shown below. The empirical formula of the compound is
Options
A.MX
B.MX2
C.M2X
D.M5X14
Solution
X = 8 × 
+ 6 × 
= 4
M = 4 ×
+ 1 = 2
So, unit cell formula of the compound is M2X4 and the empirical formula of the compound is MX2.
+ 6 × = 4 M = 4 ×
+ 1 = 2So, unit cell formula of the compound is M2X4 and the empirical formula of the compound is MX2.
