Candiumm

Title: Atomic Mass of Candium Modified from activity in Chemistry, 5th edition, (Addison-Wesley ), 2000 Purpose: To use a Candium mold to liberate the concept of atomic slew. To analyze the isotopes of Candium and calculate its atomic survey. Materials analyse of Candium Balance Procedure 1.Obtain sample of Candium 2.Separate it into its 3 isotopes. 3.Determine the amount push-down stack or individu bothy 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 host of each isotope 2. per centumageage teemingness of each isotope 3. congenator copiousness of each isotope 4. congeneric agglomerate of each isotope 5.average book of all isotopes 6. descriptor average for sexual intercourse mass 7.Percent wrongdoing Discussion: 1.Summarize what you did. 2. prepare the term isotope. 3.Explain the difference between percent abundance and congress ab undance. (Hint: What is the result when you total the unmarried 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 begin a full essay, rank it on our website: BestEssayCheap.com
