#### Part II. Data Table
- **Symbol of metal used:** Al
- **Mass of empty 8'' test tube:** 40.90 g
- **Mass of test tube and metal:** 92.5 g
- **Initial temperature of metal:** 106°C
- **Mass of water in Styrofoam cup:** 75.00 g
- **Initial temperature of water:** 21.2°C
- **Final temperature of metal and water mix:** 31.4°C
- **Specific heat of water:** 1 cal/g°C
- **Specific heat of your metal from handbook:** 0.900 J/g°C
#### Calculations (Carry out to the proper number of significant digits)
1. **Mass of metal used:**
\[
92.5 \, \text{g} - 40.90 \, \text{g} = 51.6 \, \text{g}
\]
2. **Change in temperature of metal:**
\[
\Delta T_{\text{metal}} = 106 \, \text{°C} - 31.4 \, \text{°C} = 74.6 \, \text{°C}
\]
3. **Mass of water used:**
\[
75.00 \, \text{g}
\]
4. **Change in temperature of water:**
\[
\Delta T_{\text{water}} = 31.4 \, \text{°C} - 21.2 \, \text{°C} = 10.2 \, \text{°C}
\]
5. **Heat gained by water:**
\[
q_{\text{water}} = m_{\text{water}} \times c_{\text{water}} \times \Delta T_{\text{water}}
\]
\[
q_{\text{water}} = 75.00 \, \text{g} \times 1 \, \text{cal/g°C} \times 10.2 \, \text{°C} = 765 \, \text{cal}
