Given that the mass spectrum of bromine contains peaks for both bromine atoms and diatomic bromine molecules, predict the number of peaks in the spectrum. What would be the relative height of the atomic peaks? What would be the relative height of the molecular peaks? Need a fast expert's response? Place free inquiry.

So we've been given the atomic mass off Roomie Atomic Mass has been given us 79 point and essentially the sum off these percent abundances.
So the sum of the mass times a person abundance for each respective isotope, I should give us the atomic mass. So in this expression, here, we can write that as human, we say the mass off bro mean roomie 79 a.
So we can say that Let's say the variable, eh times the person abundance just 50 point 69 plus the mass of the second isotope, which is 80 point times 49 points. And if we saw for a right, so by solving for a is essentially going to be equal to this one, is that right? So So we're gonna have basically 79 Well divided by So that is the mass for rooming.

Problem 79 Hard Difficulty Bromine has two naturally occurring isotopes Br and Br and an atomic mass of Chemistry Structure and Properties Chapter 1 Atoms. Discussion You must be signed in to discuss. Anyone else confused by the natural abundance, can someone explain? If copper has an atomic mass of Those atoms have 6 neutrons. There are a few straggler atoms that don't have 6. Those odd ones may have 7 or even 8 neutrons.
As you learn more about chemistry , you will probably hear about carbon Carbon actually has 8 neutrons 2 extra. C is considered an isotope of the element carbon. Messing with the Mass If you have looked at a periodic table , you may have noticed that the atomic mass of an element is rarely an even number.
That happens because of the isotopes. If you are an atom with an extra electron, it's no big deal. Electrons don't have much of a mass when compared to a neutron or proton. Atomic masses are calculated by figuring out the amounts of each type of atom and isotope there are in the Universe. For carbon, there are a lot of C, a couple of C, and a few C atoms. When you average out all of the masses, you get a number that is a little bit higher than 12 the weight of a C atom.
The average atomic mass for the element is actually Since you never really know which carbon atom you are using in calculations, you should use the average mass of an atom.
