Answer:
Average atomic mass of bromine
Average atomic mass of bromine= (79×49.7%) +(81×50.3%)
Average atomic mass of bromine= (79×49.7%) +(81×50.3%)=79×49.7/100 + 81×50.3/100
Average atomic mass of bromine= (79×49.7%) +(81×50.3%)=79×49.7/100 + 81×50.3/100=79×0.497+81×0.503
Average atomic mass of bromine= (79×49.7%) +(81×50.3%)=79×49.7/100 + 81×50.3/100=79×0.497+81×0.503=39.263+40.743
Average atomic mass of bromine= (79×49.7%) +(81×50.3%)=79×49.7/100 + 81×50.3/100=79×0.497+81×0.503=39.263+40.743=80.006u
