1. Chemical Formula:
* Iron(III) carbonate has the chemical formula Fe₂(CO₃)₃.
2. Atomic Masses:
* Fe (Iron): 55.845 g/mol
* C (Carbon): 12.011 g/mol
* O (Oxygen): 15.9994 g/mol
3. Calculation:
* Iron (Fe): 2 atoms * 55.845 g/mol = 111.69 g/mol
* Carbon (C): 3 atoms * 12.011 g/mol = 36.033 g/mol
* Oxygen (O): 9 atoms * 15.9994 g/mol = 143.9946 g/mol
4. Total Molar Mass:
* 111.69 g/mol + 36.033 g/mol + 143.9946 g/mol = 291.7176 g/mol
Therefore, the molar mass of iron(III) carbonate (Fe₂(CO₃)₃) is approximately 291.72 g/mol.
