The molar mass of calcium phosphate, which has the chemical formula Ca3(PO4)2, can be calculated by summing the atomic masses of all the atoms in its formula.
In calcium phosphate, there are three calcium (Ca) atoms, two phosphorus (P) atoms, and eight oxygen (O) atoms. The atomic masses for these elements are approximately:
- Calcium (Ca): 40.08 g/mol
- Phosphorus (P): 30.97 g/mol
- Oxygen (O): 16.00 g/mol
Now, let’s break down the calculation:
- Calcium: 3 x 40.08 g/mol = 120.24 g/mol
- Phosphorus: 2 x 30.97 g/mol = 61.94 g/mol
- Oxygen: 8 x 16.00 g/mol = 128.00 g/mol
Adding these together gives us the total molar mass of calcium phosphate:
120.24 g/mol + 61.94 g/mol + 128.00 g/mol = 310.18 g/mol
Therefore, the molar mass of calcium phosphate is approximately 310.18 g/mol.
