To calculate the formula weight of calcium phosphate, we first need to understand its chemical composition. Calcium phosphate is commonly represented by the chemical formula Ca3(PO4)2, which indicates that one molecule of calcium phosphate contains three calcium (Ca) atoms, two phosphate (PO4) groups. The phosphate group itself is composed of one phosphorus (P) atom and four oxygen (O) atoms.
Here’s a step-by-step breakdown of how to calculate the formula weight of calcium phosphate:
Identify the Atomic Weights:
- Calcium (Ca): 40.078 g/mol
- Phosphorus (P): 30.9738 g/mol
- Oxygen (O): 15.999 g/mol
Calculate the Weight of Each Component:
- For Calcium (Ca): 3 atoms * 40.078 g/mol = 120.234 g/mol
- For Phosphorus (P): 2 atoms * 30.9738 g/mol = 61.9476 g/mol
- For Oxygen (O): Since there are 4 oxygen atoms in each phosphate group and there are 2 phosphate groups, there are a total of 8 oxygen atoms. So, 8 atoms * 15.999 g/mol = 127.992 g/mol
Sum the Weights:
- Total formula weight = Weight of Calcium + Weight of Phosphorus + Weight of Oxygen
- Total formula weight = 120.234 g/mol + 61.9476 g/mol + 127.992 g/mol
- Total formula weight = 310.1736 g/mol
Thus, the formula weight of calcium phosphate (Ca3(PO4)2) is approximately 310.18 g/mol.
