Working with two isotopes?
Q. This problem simply confuses me. Surely it cannot be as simple as subtracting 92.58 percent from 100%... Here is the problem...I am more concerned with the problem-solving than with the answer itself. Thanks! There are two isotopes of lithium. Li-7.016 has an abundance of 92.58%. The other isotope, Li-6.015 has what percent abundance? Calculate the average atomic mass of lithium. thanks! Aahh, that's it? Ha, Thanks! Asked by Paulina - Sat Feb 9 12:55:00 2008 - - 1 Answers - 0 Comments A. The first part is as simple as subtracting 92.58 from 100. That gives you the abundance of Li-6.015. Now you have to calculate the atomic mass, which requires calculating a weighted average. Multiply the fractions (percent/100) of each isotope by it's mass, and add together. That will give the atomic weight. Answered by Dr. W. - Sat Feb 9 12:59:56 2008 From Yahoo Answer Search: "percent abundance" |
