Can you actually measure the mass of atoms using a scale like the one in this lab? Explain.
In your post, share the percent abundance and atomic mass of the isotopes in each of the three mixtures you created. Then, find a classmate's post, and calculate the average atomic mass of one of their mixtures. Include the mixture, your work, and final answer when responding to their post. Return to your post, and read the responses of your classmates. If their calculations are correct, let them know they are right. If their calculations are not correct, show them how to calculate the average atomic masses of your mixtures.
How did the average atomic mass change as you varied the percent abundance of your isotopic mixtures?
There are two stable isotopes of lithium. The atomic mass of lithium-6 is 6.02 amu, and the atomic mass of lithium-7 is 7.02 amu. The average atomic mass of lithium is 6.94 amu. Can you predict which isotope has a greater abundance based on its average atomic mass? Explain.
