The chemical formula for magnesium phosphate is Mg3(PO4)2. To calculate the molar mass, we need to determine the atomic masses of each element and multiply them by their respective subscripts in the formula.
The atomic masses are as follows:
Magnesium (Mg) = 24.31 g/mol
Phosphorus (P) = 30.97 g/mol
Oxygen (O) = 16.00 g/mol
Now let's calculate the molar mass:
Molar mass of Mg3(PO4)2 = (3 * Mg) + (2 * P) + (8 * O)
= (3 * 24.31 g/mol) + (2 * 30.97 g/mol) + (8 * 16.00 g/mol)
= 72.93 g/mol + 61.94 g/mol + 128.00 g/mol
= 262.87 g/mol
Therefore, the molar mass of magnesium phosphate (Mg3(PO4)2) is approximately 262.87 g/mol.
