The Relative Mass Calculator is designed to help you quickly determine the relative mass of an element based on its isotopic composition. This tool is invaluable for conducting precise scientific experiments, quality control in manufacturing, and educational purposes, ensuring that you have accurate data for your studies and professional work.
Formula of Relative Mass Calculator
The calculation of relative mass is based on the formula:
Where:
- Sum of isotopic mass refers to the total mass of all isotopes of an element that naturally occur.
- Relative abundance measures how prevalent each isotope is, expressed as a percentage.
Table for General Terms
Below is a table providing essential data for common elements used in relative mass calculations:
| Element | Isotope | Isotopic Mass (u) | Relative Abundance (%) |
|---|---|---|---|
| Carbon | C-12 | 12.00 | 98.93 |
| Carbon | C-13 | 13.003 | 1.07 |
| Oxygen | O-16 | 15.994 | 99.76 |
| Oxygen | O-18 | 17.999 | 0.20 |
This table can be used as a quick reference to avoid manual calculations, enhancing your efficiency in tasks requiring relative mass data.
Example of Relative Mass Calculator
Let’s walk through an example calculation for Carbon:
Relative mass of Carbon = (12.00 × 98.93 + 13.003 × 1.07) / 100 = 12.011
This example demonstrates how to input isotopic masses and their relative abundances to obtain the relative mass of an element.
