1.	In orthorhombic , the value of a, b and c are respectively `4.2Å, 8.6 Å and 8.3Å` .Given the molecular mass of the solur is `155 gm mol^(-1)` and that of density is `3.3 gm//cc` the number of formula unit per unit cell isA. 2B. 3C. 4D. 6
Answer» Correct Answer - C `Z=(VxxN_(0)xxd)/(M)` `=(4.2xx8.6xx8.3xx10^(-24)xx6.023xx10^(23)xx3.3)/(155)=3.84=4`
