The Abundancy Ratio Calculator determines the proportion of a specific isotope within a sample containing multiple isotopes. This calculation is crucial for understanding the composition and behavior of materials, particularly in scientific research and industrial applications.
Formula of Abundancy Ratio Calculator
To calculate the abundancy ratio more accurately, it’s important to account for all isotopes in the sample. Here’s the detailed formula:
Abundancy Ratio for Isotope A = Number of Atoms of Isotope A / (Number of Atoms of Isotope A + Number of Atoms of Isotope B + Number of Atoms of Isotope C + … + Number of Atoms of Isotope N)
Where:
- Number of Atoms of Isotope A is the count of the specific isotope you are interested in.
- Number of Atoms of Isotope B, C, …, N are the counts of all other isotopes in the sample.
To express it as a percentage:
Abundancy Ratio (%) for Isotope A = (Number of Atoms of Isotope A / (Number of Atoms of Isotope A + Number of Atoms of Isotope B + Number of Atoms of Isotope C + … + Number of Atoms of Isotope N)) * 100
Common Abundancy Ratios Table
Here is a table of pre-calculated abundancy ratios for some common isotopes to help you quickly find the values without performing each calculation manually:
| Isotope | Number of Atoms | Total Atoms in Sample | Abundancy Ratio (%) |
|---|---|---|---|
| Isotope A | 50 | 200 | 25% |
| Isotope B | 30 | 200 | 15% |
| Isotope C | 70 | 200 | 35% |
| Isotope D | 50 | 200 | 25% |
Example of Abundancy Ratio Calculator
Let’s walk through an example to illustrate how the Abundancy Ratio Calculator works. Suppose you have a sample with the following isotopes:
- Isotope A: 40 atoms
- Isotope B: 30 atoms
- Isotope C: 50 atoms
- Isotope D: 80 atoms
First, calculate the total number of atoms in the sample:
Total Atoms = 40 (A) + 30 (B) + 50 (C) + 80 (D) = 200
Next, calculate the abundancy ratio for Isotope A:
Abundancy Ratio for Isotope A = 40 / 200 = 0.2
Convert it to a percentage:
Abundancy Ratio (%) for Isotope A = 0.2 * 100 = 20%
Thus, the abundancy ratio of Isotope A in this sample is 20%.
