![### Experiment: Calculating the Density of a 10% Aqueous Solution of Sodium Chloride (NaCl)
#### Objective:
To determine the density of a 10% aqueous solution of sodium chloride using experimental data.
#### Procedure:
A student performed an experiment to calculate the density of a 10% aqueous solution of sodium chloride, NaCl. The student collected the following data for two trials:
#### Data Collected:
- **Trial 1:**
- Mass of empty graduated cylinder: 19.87 g
- Mass of cylinder + sodium chloride solution: 30.65 g
- Volume of sodium chloride solution: 10.0 mL
- **Trial 2:**
- Mass of empty graduated cylinder: 16.35 g
- Mass of cylinder + sodium chloride solution: 31.25 g
- Volume of sodium chloride solution: 15.0 mL
#### Results Table:
The table summarizes the data collected and outlines the subsequent steps to calculate the density.
**Table: Density of 10% Aqueous Solution of Sodium Chloride (NaCl)**
| | Trial 1 | Trial 2 |
|--------------------------|---------------|---------------|
| Mass of empty graduated cylinder | 19.87 g | 16.35 g |
| Mass of cylinder + sodium chloride solution | 30.65 g | 31.25 g |
| Mass of sodium chloride solution | (calculated) | (calculated) |
| Volume of sodium chloride solution | 10.0 mL | 15.0 mL |
| Density of solution | (calculated) | (calculated) |
| Average density | (calculated) | (calculated) |
#### Calculations:
1. **Mass of Sodium Chloride Solution:**
- **Trial 1:** \( 30.65 \, \text{g} - 19.87 \, \text{g} = 10.78 \, \text{g} \)
- **Trial 2:** \( 31.25 \, \text{g} - 16.35 \, \text{g} = 14.90 \, \text{g} \)
2. **Density of Solution:**
- **Formula:** \( \text{Density} = \frac{\text{Mass}}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F715f1fc4-4a71-4448-9e5a-101723170792%2F61897332-b65c-4fba-9926-60fe17663401%2Ftqh2n3q.jpeg&w=3840&q=75)
