SMALL-SCALE LAB: The Atomic Mass of Candium OBJECTIVES: To analyze the isotopes of candium and to swan its nuclear push-down store. PROCEDURE: 1. A sample of Candium was contained. 2. The four isotopes were detached into groups A, B, C, D and measured the potful of each isotope. 3. Counted the number of atoms in each sample. 4. Used the table to record our measured and effort data. HYPOTHESIS: As the coitus copiousness increases the percent teemingness increases. Which causes the cor coincidence to be positive. DATA:  | A| B| C| D| Totals| | Total mass (grams) | 14.59| 16.33|  11.96|  41.83|  84.71| | Number|  14|  19|  17|  39|  89| | Average mass (grams)|  1.0|  .86|  .70|  1.1|  .9518| | | | | | | .915| | relation back copiousness|  .16|  .21|  .19|  .44|  1| | | | | | | 1| | Percent abundance|  16%|  21%|  19%|  44%|   deoxycytidine monophosphate%| | | | | | | 100%| | congress mass|  .16|  .18|   .13|  .48|  | | | | | | | 95.18| | | | | | | | | | | | | | .95| | | | | | | | | ANAYLASIS: CONCLUSION: 1. The difference between carnal knowledge abundance and percent abundance is that carnal knowledge abundance is a simile between the isotopes.

Percent abundance is when you compare the extremes. The resolvent when your total the individual percent abundances you get 100%. various(prenominal) relative abundances also totals to 1. 2. Relative abundance tells you how much of a busy isotope is present in a given marrow of sample. 3. The totals for number mass and relative mass differ in some(prenominal) ways. First of all the relative mass is alway s little(a) than the average mass. Secondl! y, the average mass is closer to one, while the relative mass is closer to zero. The average mass and the relative mass represent the atomic mass, because the atomic mass is how much an ingredient weighs. We had to weigh the Candium in order to find the mass, which then stood for its atomic mass....If you want to get a full essay, order it on our website: OrderEssay.net
