![**SHOW ALL CALCULATIONS.**
1. **Mass of calcium phosphate sample plus weighing paper:**
- Recorded Value: 2.332 g
2. **Mass of weighing paper:**
- Recorded Value: 0.184 g
3. **Mass of calcium phosphate sample:**
- Calculation: \( 2.332 \, \text{g} - 0.184 \, \text{g} = 2.148 \, \text{g} \)
4. **Molar mass of calcium phosphate (\(\text{Ca}_3(\text{PO}_4)_2\)):**
- Calculation:
\[
40.08(3) + [30.97 + 16.00(4)]2 = 310.18 \, \text{g/mol}
\]
5. **Number of moles of calcium phosphate in your sample:**
- Calculation:
\[
\frac{2.148 \, \text{g} \times 1 \, \text{mole}}{310.18 \, \text{g/mol}} = 0.006925 = 7.025 \times 10^{-3} \, \text{moles}
\]
