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
