A compound `M_(p)X_(q)` has cubic close packing `(ccp)` arrangement of `X`. Its unit cell structure is shown below. The empirical formula of the compound is

A

`MX`

B

`MX_(2)`

C

`M_(2)X`

D

`M_(5)X_(14)`

Text Solution

Verified by Experts

The correct Answer is:
B
Number of `M` atoms `= 1/4 xx 4 + 1 = 1 + 1 = 2`
Number of `X` atoms `= 1/2 xx 6 + 1/8 xx 8 = 3 + 1 = 4`
So, formula of compound is `M_(2)X_(4) = MX_(2)`
