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%.
