Taking a chance here: Give the masses of the three most abundant Br2O molecules? kind of chemistry but...there is not many people in the other sections...

Question

anonymous · Answer

2( Br) + (O)

anonymous · Answer

i'm assuming that's subscript 2 for Br

anonymous · Answer

yeah it is

anonymous · Answer

2(79.904) + (15.9994)

anonymous · Answer

175.8074

anonymous · Answer

there are three different masses apparently? and i have to type them in in increasing order

anonymous · Answer

well i mean...Br would be 79.904,  Br2 would be 159.908 and O would be 15.9994

anonymous · Answer

okso those are the most abundant molecules?

anonymous · Answer

Br2 is going to be the most abundant of them

anonymous · Answer

like almost 91% to oxygen's 9%

anonymous · Answer

soit would be 16,80,160?

anonymous · Answer

yea if your only required to give 2 sig figures

This gives a hint as to how to answer the question http://www.cramster.com/answers-apr-11/chemistry/br2o-naturally-occurring-bromine-composed-isotopes-50_1265486.aspx?rec=0 They are asking about isotopes abundances.

anonymous · Answer

well...he was taking a shot asking...i was taking a shot answering...haven't done chem in over a year

anonymous · Answer

thank you!!..but i dont have a cramster account :/

phi · Answer

Apparently there are 2 isotopes for Br and 3 for O, or 6 different combinations

phi · Answer

no wait! There are 2 Br in the molecule.
So the answer is 
1) 2 most common Br plus most common O
2) 1 of each Br plus most common O
3) 2 of the "rarer" Br plus most common O

phi · Answer

That's my best shot, not being a chemist
