Final answer:
To convert 0.500 mol of Ca3(PO4)2 to grams, multiply the number of moles by the formula mass of calcium phosphate, which equals 155.0885 grams.
Step-by-step explanation:
To convert 0.500 mol of Ca3(PO4)2 to grams, we'll first determine the formula mass of the compound, which is calcium phosphate. Using atomic mass units (amu), we can calculate this:
- For Calcium (Ca): (3 atoms) × (40.078 amu/atom) = 120.234 amu
- For Phosphorus (P): (2 atoms) × (30.973761 amu/atom) = 61.947522 amu
- For Oxygen (O): (8 atoms) × (15.9994 amu/atom) = 127.9952 amu
This gives us a total formula mass for Ca3(PO4)2 of 310.177 amu. To get the mass in grams, we multiply the moles by the formula mass:
0.500 moles × 310.177 g/mole = 155.0885 grams of Ca3(PO4)2.
