Question

The table below displays four solutions made by dissolving salt in water.
Solution | Mass of NaCI (g) | Volume of water (mL)
A | 5.0 | 50.0
B | 5.0 | 75.0
C | 5.0 | 100.0
D | 5.0 | 125.0
Which of the solutions has the highest concentration of salt?

Answer 1

To determine which solution has the highest concentration of salt (NaCl), we can calculate the concentration of each solution using the formula:

\[ \text{Concentration (g/mL)} = \frac{\text{mass of NaCl (g)}}{\text{volume of water (mL)}} \]

Now, let's calculate the concentration for each solution:

1. **Solution A**:
\[
\text{Concentration A} = \frac{5.0 \, \text{g}}{50.0 \, \text{mL}} = 0.1 \, \text{g/mL}
\]

2. **Solution B**:
\[
\text{Concentration B} = \frac{5.0 \, \text{g}}{75.0 \, \text{mL}} \approx 0.0667 \, \text{g/mL}
\]

3. **Solution C**:
\[
\text{Concentration C} = \frac{5.0 \, \text{g}}{100.0 \, \text{mL}} = 0.05 \, \text{g/mL}
\]

4. **Solution D**:
\[
\text{Concentration D} = \frac{5.0 \, \text{g}}{125.0 \, \text{mL}} = 0.04 \, \text{g/mL}
\]

Now we can compare the concentrations:

- Concentration A: 0.1 g/mL
- Concentration B: 0.0667 g/mL
- Concentration C: 0.05 g/mL
- Concentration D: 0.04 g/mL

The solution with the highest concentration of salt is **Solution A** with a concentration of **0.1 g/mL**.
