"Hello, I'm having a little problem on this percent abundance thing in our chemistry... The problem goes:
The atomic weight of Gallium is 69.72 amu. The masses of the naturally occuring isotopes are 68.9257 amu for Ga69 and 70.9249 amu for Ga71. Calculate the percent abundance of each isotope.
"I am confused coz when I look for formulas, there are lots of variations. This is the first time I've ever joined PhysicsForums, but I think this is totally reliable. I'm looking forward to a very nice answer, as soon as possible, if possible. Thanks =)"
