Ecomine, (Br atomic number 35), has an average weighted atomic mass of 79.904 atamic mass units (amu). if bromine has two isotopes, whose percent abundance is 50% each (itotope 1= mass ?, abundacce =50%, isotope 2 - mass ? abundance =50% ), what should the mass of isotopes be certe down the expected mass of isotope 1 and isotope 2 Hint The mass wil be wemen to three decimal flaces. Wille the mass for the fret isolope in the first answer box and the secend isotope in the second answer bex to three decimal daces. No need to enser perod or extra scaces or unh sbbreviation. For axample dy you thought the answer was 1.234567 antu write it as (1.234) not (1.234amu) or (t 23 amu) or (12345 arma) Second Hirt selece 1 is heaver than isctoge 2 . (Yrpoint per-part, wotal =1 point) Remember the real answer box is not 0 but a ernply ipace to type. I am using 0 as an example of an empty epaco where you hand type your
