Answer:

8 minutes

Explanation:

G(g)                 T(min)

100 --------------- 0

50-------------------2

25 -------------------4

12.5  ---------------  6

6.25 ----------------8

     another    way:

100/6.25 = 16

  16 = 2⁴       ( 4 half lives)    

Each half life is 2 minutes

so 4 half lives will be 8 minutes
