In the following reaction sequence, the amount of $\mathbf{D}$ (in g ) formed from 10 moles of acetophenone is $\_\_\_\_$ . (Atomic weights in $\mathrm{g} \mathrm{mol}^{-1}: \mathrm{H}=1, \mathrm{C}=12, \mathrm{~N}=14, \mathrm{O}=16, \mathrm{Br}=80$. The yield (\%) corresponding to the product in each step is given in the parenthesis)
