Answer:
80 u
Explanation:
Average atomic mass of Br=[AtomicmassofBr×percentage + AtomicmassofBr × percentage ]/100
or avg. mass = m1x1 + m2x2 / x1 + x2
i. e. =[79×49.7 + 81×50.3]/100
=80.006u

Answer:
Percentage of 79/35 Br isotope = 49.7
Percentage of 81/35 Br isotope = 50.3
Average atomic mass = 49.7 x 79 +50.3 x 81/100
= 3926.3 + 4074.3/100
= 8000.6/100
=80.006
