1.	The density of `KBr` is `2.75 g cm^(-3)`. The length of the unit cell is `654` pm. Atomic mass of `K = 39, Br = 80`. Then what is true about the predicted nature of the solid?A. Face centred cubicB. simple cubic systemC. body centred cubic systemD. none of these
Answer» Correct Answer - A `Z=(d xxa^(3)xxN_(0)xx10^(-30))/(M)" "(becausea=cm)` `=(2.85xx(654)^(3)xx(6.02xx10^(23))xx10^(-30))/(39+80)=3.9~~4` Hence, it is face-centred.
