To calculate the molar mass of calcium phosphate, we first need to understand its chemical formula, which is Ca3(PO4)2. This formula indicates that one molecule of calcium phosphate contains three calcium (Ca) atoms, two phosphate (PO4) groups, with each phosphate group consisting of one phosphorus (P) atom and four oxygen (O) atoms.
The atomic masses of the atoms in calcium phosphate, based on the periodic table, are approximately: - Calcium (Ca): 40.08 g/mol - Phosphorus (P): 30.97 g/mol - Oxygen (O): 16.00 g/mol
Given the formula Ca3(PO4)2, we calculate the molar mass as follows: 1. Calcium contribution: 3 atoms * 40.08 g/mol = 120.24 g/mol 2. Phosphorus contribution: 2 atoms * 30.97 g/mol = 61.94 g/mol 3. Oxygen contribution: 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 * 16.00 g/mol = 128.00 g/mol
Adding these contributions together gives us the molar mass of calcium phosphate: 120.24 g/mol (calcium) + 61.94 g/mol (phosphorus) + 128.00 g/mol (oxygen) = 310.18 g/mol
Therefore, the molar mass of calcium phosphate (Ca3(PO4)2) is approximately 310.18 grams per mole.
