A molecule \[{{A}_{2}}B\] (M wt. = 166.4) occupies triclinic lattice with a = 5\[\overset{o}{\mathop{A}}\,\], b = 8\[\overset{o}{\mathop{A}}\,\], and c = 4\[\overset{o}{\mathop{A}}\,\]. If the density of \[A{{B}_{2}}\] is \[5.2\,g\,c{{m}^{-\,3}}\], find the number of molecules present in one unit cell.
