Computing Molar Mass of Iron(II) Carbonate Step by Step
Molar Mass of Iron(II) Carbonate: Step-by-Step Calculation
1. Identify Element Counts
Read FeCO3 and list how many atoms of each element are present:
- 1 atom of Iron (Fe)
- 1 atom of Carbon (C)
- 3 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Iron (Fe) ~= 55.845 g/mol
- Carbon (C) ~= 12.011 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Iron (Fe): 1 x 55.845 = 55.840 g/mol
- Carbon (C): 1 x 12.011 = 12.010 g/mol
- Oxygen (O): 3 x 15.999 = 48.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 55.845 + 1 x 12.011 + 3 x 15.999)
Molar Mass = 55.840 + 12.010 + 48.000
Molar Mass = 115.850 g/mol
Final rounded value shown on this page: 115.85 g/mol.
