Question

If bromine atom is available in the form of, say, two isotopes
35 Br (49.7%) and 3Br (50.3%), calculate the average atomic
mass of bromine atom.
​

Answer 1

Explanation:

= (35×49.7/100)+(37×50.3/100)

=36.006

Answer 2

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
