Calculate the average atomic weight of Fe if abundance of isotopes 54 ...
Understanding Average Atomic Weight
The average atomic weight of an element is calculated by considering the weights of its isotopes and their relative abundances. For Iron (Fe), we have three isotopes with the following data:
- 54Fe: 5% abundance
- 56Fe: 90% abundance
- 57Fe: 5% abundance
Steps to Calculate Average Atomic Weight
1. Identify Isotope Weights and Abundances
- 54Fe: Weight = 54 amu, Abundance = 0.05
- 56Fe: Weight = 56 amu, Abundance = 0.90
- 57Fe: Weight = 57 amu, Abundance = 0.05
2. Calculate Contribution of Each Isotope
- Contribution of 54Fe = 54 x 0.05 = 2.7
- Contribution of 56Fe = 56 x 0.90 = 50.4
- Contribution of 57Fe = 57 x 0.05 = 2.85
3. Sum the Contributions
- Total Contribution = 2.7 + 50.4 + 2.85 = 55.95 amu
4. Calculate Average Atomic Weight
The average atomic weight of Fe is approximately 55.95 amu.
Conclusion
The average atomic weight of Iron (Fe) considering the isotopes and their respective abundances is 55.95 amu. This value plays a crucial role in understanding the element's properties and behaviors in various chemical reactions and applications.
