Expert Solution

answer : 1 mole

only two possible reaction with Bromine

(1) Br2   +2 I - -------------------> 2Br- + I2

     2          5                           0         0 ---------------> initial

     0           3                          2         2-------------> after reaction

(2) Cl2   +2 Br- -----------------> 2Cl-   + Br2

      2          1                             0         0

       1         0                             1          1---------------> after reaction
