Chromium has four main isotopes.
50Cr, 52Cr, 53Cr, and 54CR
50Cr- 4.43% relative abundance 49.946 Isotopic Mass
52Cr- ? % relative abundance 51.941 Isotopic Mass
53Cr- ? % relative abundance 52.946 Isotopic Mass
54Cr- 2.28% relative abundance 53.939 Isotopic Mass
Average Mass = 51.996
Determine the two unkowns.... really stumped could use some help.
I know how to do the simple 65Cu, 63Cu with the 1-x but I just don't know how to put this one into an equation.
I suppose using two variables may be the key but I just don't know how to arrange it.
