Computing Molar Mass of Cobalt(II) Phosphate Step by Step
Molar Mass of Cobalt(II) Phosphate: Step-by-Step Calculation
1. Identify Element Counts
Read Co3(PO4)2 and list how many atoms of each element are present:
- 3 atoms of Cobalt (Co)
- 2 atoms of Phosphorus (P)
- 8 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Cobalt (Co) ~= 58.933 g/mol
- Phosphorus (P) ~= 30.974 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Cobalt (Co): 3 x 58.933 = 176.800 g/mol
- Phosphorus (P): 2 x 30.974 = 61.950 g/mol
- Oxygen (O): 8 x 15.999 = 127.990 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (3 x 58.933 + 2 x 30.974 + 8 x 15.999)
Molar Mass = 176.800 + 61.950 + 127.990
Molar Mass = 366.740 g/mol
Final rounded value shown on this page: 366.74 g/mol.
