Candiumm

Title: Atomic Mass of Candium Modified from activity in Chemistry, 5th edition, (Addison-Wesley ), 2000 Purpose: To use a Candium mold to relinquish the concept of atomic slew. To analyze the isotopes of Candium and calculate its atomic push-down storage. Materials discharge of Candium Balance Procedure 1.Obtain sample of Candium 2.Separate it into its 3 isotopes. 3.Determine the amount locoweed or singlel(a)y isotope. 4.Count the numbers of each isotope. 5.Record info and calculations in the data chart (see data chart below for details) 1.average ken of each isotope 2. portionage teemingness of each isotope 3. congenator abundance of each isotope 4. congeneric throne of each isotope 5.average bulk of all isotopes 6. descriptor average for sexual intercourse mass 7.Percent hallucination Discussion: 1.Summarize what you did. 2. prepare the term isotope. 3.Explain the difference between portion abundance and congress abundan ce. (Hint: What is the result when you total the individual percent abundance set for each isotope?

What is the result when you total the individual relative abundance value for each isotope?) 4.Compare the total values for rows 3 and 6 in the data table. How does the average mass differ from the relative mass? 5.Compare your value for relative mass to that of the class. 6.Comment on your percent error, sources of error in the activity, and provide suggestions for improvement. 7.Comment on how the activity is a model for calculating atomic mass of real elements. Conclusion: The relative m ass of Candium is ____________ ± __________! If you want to labour a full essay, rank it on our website: BestEssayCheap.com
