1.	A molecule `A_(2)B (Mw = 166.4)` occupies triclinic lattice with `a = 5 Å, b = 8 Å`, and `c = 4 Å`,. If the density of `AB_(2)` is `5.2 g cm^(-3)`, the number of molecules present in one unit cell is
Answer» Correct Answer - 3 Volume of unit cell `=axxbxxxc` `=5xx10^(-8)xx8xx10^(-8)xx4xx10^(-8)` `=1.6xx10^(-22)cm^(3)` Mass of unit cell `=1.6xx10^(-22)xx5.2` `=8.32xx10^(-22)g` No. of molecules in one unit cell `=(8.32xx10^(-22)xx6xx10^(23))/(166.4)=3`
