Question
Hey guys,I'm having a lot of trouble with this problem:
Boron has two naturally occurring isotopes, 10B (19.9%)and 11B (80.1%). Although the B2 moleculedoes not exist naturally on Earth, it has been produced in the laband observed in stars. How many different B2 moleculesare possible? What are the masses and percent abundances ofeach?
I guess don't really understand what the question is even asking meto do. I'm not sure how to determine how many molecules arepossible, and as far as I can tell, it doesn't say anything aboutthis in the textbook. Any help at all would be greatlyappreciated!
Explanation / Answer
From the given data :
we can calculate the Average atomic weight ofBoron
Average atomic weight = 19.9 x 10+ 80.1 x 11 / 19.9 + 80.1
