58.9332*(1-X)+59.9338*x=58.9901
solve for x, which is the decimal fraction of Co60, then multipy it by 1.8516 to get the mass of Co60
Let x = fraction of Co60; then
1-x = fraction of Co59.
mass Co59(1-x) + mass Co60(x) = 58.9901
Solve for x (and multiply by 100 if you want percent, then
fraction x 1.8516g = mass Co 60 in the 1.8616g sample.
When I worked it out I got .105 g, is that correct?
I have to get this question right, in order to make a B on my assignment
Yes.
