online references for nuclear chem?
« on: November 29, 2004, 08:03:54 AM »
Greetings everyone!

I would like to ask for any online links for Nuclear Chemistry?  I have been boggled by a certain Nuclear Chemistry problem.  For example, you're given a certain nuclear activity of 2000 cpm for a mass of 50 mg, and 500 cpm for a mass of 60 mg.  Then you are asked for the mass of the original sample?  I saw from the Mortimer book the formula: No/N = (activity)0/(activity), but I can't figure out a formula of finding for the mass of the original sample.  I'm trying to solve it without using a calculator...

Hope you can clear this up guys.  Thanks.

Regards,
Tashkent

I'm not too sure. How about working from basic principles?

-dN/dt = kN where N is number of radioactive nuclei, k: constant
