Chapter 32, Problem 32-15(choose chapter or problem)
In an isotope dilution experiment, chloride was determincd by adding 5.0 mg ofsodium chloride containing 38et (e1l2 = 37.3 min) to a sample. The specific activityof the added NaCl was 4.0 X 10' cps/mg. What was the total amount of chloridepresent in the original sample if 400 mg of pure AgCI was isolated and if thismaterial had a counting rate of 35 cps above background 148 min after the additionof the radiotracer?
