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. MXB. `MX_(2)`C. `M_(2)X`D. `M_(5)X_(14)`

Answer» Correct Answer - B
No. of M atoms `=(1)/(4)xx4+1=1+1=2`
No. of X atoms `=(1)/(2)xx6+(1)/(8)xx8+3+1=4`
