Consider the following sequence of reactions to produce major product (A) Molar mass of product (A) is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$. (Given molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1}$ of $\displaystyle \mathrm{C}: 12, \mathrm{H}: 1, \mathrm{O}: 16, \mathrm{Br}: 80, \mathrm{~N}: 14, \mathrm{P}: 31$ )
