Question

If Bromine atom is available in the form of, say, two isotopes 79 35Br(49.7%)& 81 35Br(50.3%), Calculate the average atomic mass of Bromine atom?

Answer 1

Average atomic mass of Br => (79*49.7/100) + (81*50.3/100)
=39.26+40.74
=80u

Hope it helps!

Answer 2

_/\_Hello mate__here is your answer--

_______________________

The average atomic mass of bromine

={ (79 x 49.7)+ (81 x 50.3) }/100

= (3926.3 + 4074.3)/100

= 8000.6/100

= 80 u

I hope, this will help you.☺

Thank you______❤
