If khan academy started it's own university, most universities would loose their students

What if it is not a pure element, but a compound?

instead of interpreting the graph as 7% for the 87amu isotope, and if we put 8% instead, the average atomic mass is closer to that of rubidium's. is it wrong if we interpret the last "uncertain" significant figure a little off an end up getting a different element?
