Button type | Number of buttons | Mass of sample (g) | Atomic mass of isotopes | % Abundance |
2 holes | 25 | 44.64 | ||
3 holes | 15 | 23.52 | ||
4 holes | 12 | 15.19 |
To complete the last to columns, and then calculate the atomic mass of the element Buttonium.
A) To complete the atomic mass of each isotope , obtain the average mass of a button in each sample by dividing the mass of the sample by the number of buttons in the sample. Show your calculations here for each sample. Write the results in the corresponding place on the table.
B) To complete the % abundance of each isotope, you need to divide the number of buttons in the sample by the overall total number of buttons (add the number of buttons in all samples) What is the number of buttons altogether ________. Show your calculation for for the % abundance of each isotope. Write the results in the corresponding place on the table.
C) calculate the atomic mass of the element buttonium by weighed average:
