2. Medicine: In chelation therapy, this compound can help remove heavy metals from the body.
3. Analytical Chemistry: It is used in various titration methods to determine the concentration of metal ions in solutions.

Calculating the Molar Mass of Na Fe EDTA · 3H2O

To understand the molar mass of Na Fe EDTA · 3H2O, we need to break down its components and calculate the mass of each atom in the compound:

1. Sodium (Na): 1 atom × 22.99 g/mol = 22.99 g/mol
2. Iron (Fe): 1 atom × 55.85 g/mol = 55.85 g/mol
3. Carbon (C): 8 atoms × 12.01 g/mol = 96.08 g/mol
4. Hydrogen (H): 13 atoms × 1.01 g/mol = 13.13 g/mol
5. Nitrogen (N): 2 atoms × 14.01 g/mol = 28.02 g/mol
6. Oxygen (O): 10 atoms × 16.00 g/mol = 160.00 g/mol
7. Water (H2O): 3 molecules × (2 × 1.01 + 16.00) g/mol = 3 × 18.02 g/mol = 54.06 g/mol

Total Molar Mass Calculation

Now, we add all these values together to find the total molar mass of Na Fe EDTA · 3H2O:

\[
\text{Total Molar Mass} = 22.99 + 55.85 + 96.08 + 13.13 + 28.02 + 160.00 + 54.06 = 430.13 \text{ g/mol}
\]

Conclusion

The molar mass of Na Fe EDTA · 3H2O is approximately 430.13 g/mol. Understanding this molar mass is essential for its applications in various fields, ensuring accurate measurements in laboratory settings and effective use in agriculture and medicine. By knowing the molar mass, researchers and practitioners can better formulate solutions and apply this important chelating agent effectively.

If you are involved in agricultural science, chemistry, or any related field, understanding the implications of the molar mass of compounds like Na Fe EDTA · 3H2O will enhance your work and contribute to better outcomes in your projects.
