📘 Description

The Average Atomic Mass Calculator helps determine the average atomic mass of an element based on the masses of its isotopes and their relative abundances. 

🧪 Uses 

Understand atomic structure in chemistry classes. Solve isotope-related questions in exams. Quickly calculate average atomic mass for lab reports or research. 

📝 Instructions 

 1. Enter the mass of the first and second isotopes (in atomic mass units, u). 

2. Enter their corresponding abundance percentages. 

3. Click Calculate to find the average atomic mass. 

 Note: This version supports two isotopes. For more, the code can be expanded.

🧮 Formula Used 

 $$ \text{Average Atomic Mass} = (m_1 \times \frac{a_1}{100}) + (m_2 \times \frac{a_2}{100}) $$ 

 Where: $m_1, m_2$: masses of the isotopes $a_1, a_2$: relative abundances in % --- Let me know if you want a version with 3+ isotopes,
