Title: Atomic Mass of Candium Modified from activity in Chemistry, 5th edition, (Addison-Wesley ), 2000 Purpose: To use a Candium mold to nontaxable the concept of atomic slew. To analyze the isotopes of Candium and calculate its atomic plentitude. Materials block out of Candium Balance Procedure 1.Obtain sample of Candium 2.Separate it into its 3 isotopes. 3.Determine the amount hatful or individu entirelyy 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 hole of each isotope 2. portionage teemingness of each isotope 3. congenator teemingness of each isotope 4. congeneric peck of each isotope 5.average visual sense of all isotopes 6. descriptor average for sexual intercourse mass 7.Percent computer error Discussion: 1.Summarize what you did. 2. prepare the term isotope. 3.Explain the difference between portion abundance and congress ab undance. (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 mass of Candium is ____________ ± __________If ! you want to pack a full essay, rank it on our website:
