An element is a mixture of two isotopes. One isotope has an atomic mass of 34.969 amu and an abundance of 64.88%. The other isotope has an atomic mass 36.966 amu. Create a data table for this element like the one shown in #3. Calculate the average atomic mass of the element, and then use your periodic table to identify the element.

Write a conclusion to this lab in which you: restate the purpose, summarize your procedure and data recorded, explain the math, and finally give your results. Also, in your conclusion, explain the concept of a weighted average, and how it applies to the determination of the average atomic mass of the elements on the Periodic Table.
Remember, here is a great guide for writing your conclusion:1) Restate the purpose2) Summarize the procedure and data collection3) Discuss any important principles / equations used4) Explain the graphs and/or math5) Report your results
Also, please include any other interesting information you would like to add.
