**DATA**

1. **Mass of empty beaker**: 49.7 g

2. **Volume of NaCl solution**: 10.0 mL

3. **Mass of beaker and NaCl solution**: 62.2 g

4. **Mass of beaker and dry NaCl**: 55.2 g

**CALCULATIONS** (show all of your work)

5. **Mass of NaCl solution**

   \[
   \text{mass of beaker and NaCl solution} - \text{mass of beaker} \\
   62.2 \, \text{g} - 49.7 \, \text{g} = 12.5 \, \text{g}
   \]

6. **Mass of dry NaCl**

   \[
   \text{mass of beaker and dry NaCl} - \text{mass of beaker} \\
   55.2 \, \text{g} - 49.7 \, \text{g} = 5.59 \, \text{g}
   \]

7. **Mass percent of NaCl solution**

   \[
   \left(\frac{\text{mass of dry NaCl}}{\text{mass of NaCl solution}} \times 100\right) \\
   \left(\frac{5.59}{12.5} \times 100\right) = 44.72\% \, (\text{m/m})
   \]

8. **Mass/volume percent of NaCl solution**

   \[
   \left(\frac{\text{mass of dry NaCl}}{\text{volume of NaCl solution}} \times 100\right) \\
   \left(\frac{5.59}{10.0} \times 100\right) = 55.9\% \, (\text{m/v})
   \]

#### Determination of NaCl Solution Parameters

1. **Moles of NaCl:**
   \[
   \text{Moles of NaCl} = \frac{\text{mass of dry NaCl}}{\text{molar mass of NaCl}}
   \]
   _______ moles

2. **Volume of NaCl Solution in Liters:**
   \[
   \text{Volume of NaCl solution in liters} = \frac{\text{volume of NaCl solution in mL}}{1000}
   \]
   _______ L

3. **Molarity of NaCl Solution:**
   \[
   \text{Molarity of NaCl solution} = \frac{\text{moles of NaCl}}{\text{liters of NaCl}}
   \]
   _______ M

#### Questions for Practice

1. **Calculate the Mass Percent (m/m):**
   Calculate the mass percent (m/m) of a MgBr₂ solution that contains 5.80 g of MgBr₂ in 45.0 g of solution.
