Chlorine Isotopes
« on: September 07, 2006, 09:20:29 PM »
A college problem...

Chlorine consists of 2 stable isotopes. Cl with a mass of 35 and Cl with a mass of 37.  32 Percent of the chlorine in an insteller grain are found to be Cl with a mass of 35.  What is the atomic weight of chlorine in this sample?

Just calculate mean mass from a percent content (32 and 68 %)
