calculate the percentage of each isotope present in the following mixtures:
a) a mixture of 107 Ag and 109 Ag has an average mass of 107.9u
I really forget how to do this, and I have no notes on it, so any help would be appriciated, This is science 10 btw thnxHow to calculate percentage of an isotope in a mixture?
Let X = fraction of mixture that is 107 Ag
107X + 109(1-X) = 107.9
107X - 109X = 107.9 - 109
-2X = -1.1
X = 0.55 (55% 107 Ag)
1-X = 0.45 (45% 109 Ag)
